AMD SDHC 0x7906 requires a hard reset to clear all internal state.
Otherwise it can get into a bad state where the DATA lines are always
read as zeros.
This change requires firmware that can transition the device into
D3Cold for it to work correctly. If the firmware does not support
transitioning to D3Cold then the power state transitions are a no-op.

The SD host controller specification defines 3 types software reset:
software reset for data line, software reset for command line and software
reset for all. Software reset for all means this reset affects the entire
Host controller except for the card detection circuit.
In sdhci_runtime_resume_host() we always do a software "reset for all",
which causes the Spreadtrum variant controller to work abnormally after
resuming. To fix the problem, let's do a software reset for the data and
the command part, rather than "for all".
However, as sdhci_runtime_resume() is a common sdhci function and we don't
want to change the behaviour for other variants, let's introduce a new
in-parameter for it. This enables the caller to decide if a "reset for all"
shall be done or not.

Problem:
The card detect IRQ does not work with modern BIOS (that want
to use _DSD to provide the card detect GPIO to the driver).
Details:
The mmc core provides the mmc_gpiod_request_cd() API to let host drivers
request the gpio descriptor for the "card detect" pin.
This pin is specified in the ACPI for the SDHC device:
* Either as a resource using _CRS. This is a method used by legacy BIOS.
(The driver needs to tell which resource index).
* Or as a named property ("cd-gpios"/"cd-gpio") in _DSD (which internally
points to an entry in _CRS). This way, the driver can lookup using a
string. This is what modern BIOS prefer to use.
This API finally results in a call to the following code:
struct gpio_desc *acpi_find_gpio(..., const char *con_id,...)
{
...
/* Lookup gpio (using "<con_id>-gpio") in the _DSD */
...
if (!acpi_can_fallback_to_crs(adev, con_id))
return ERR_PTR(-ENOENT);
...
/* Falling back to _CRS is allowed, Lookup gpio in the _CRS */
...
}
Note that this means that if the ACPI has _DSD properties, the kernel
will never use _CRS for the lookup (Because acpi_can_fallback_to_crs()
will always be false for any device hat has _DSD entries).
The SDHCI driver is thus currently broken on a modern BIOS, even if
BIOS provides both _CRS (for index based lookup) and _DSD entries (for
string based lookup). Ironically, none of these will be used for the
lookup currently because:
* Since the con_id is NULL, acpi_find_gpio() does not find a matching
entry in DSDT. (The _DSDT entry has the property name = "cd-gpios")
* Because ACPI contains DSDT entries, thus acpi_can_fallback_to_crs()
returns false (because device properties have been populated from
_DSD), thus the _CRS is never used for the lookup.
Fix:
Try "cd" for lookup in the _DSD before falling back to using NULL so
as to try looking up in the _CRS.
I've tested this patch successfully with both Legacy BIOS (that
provide only _CRS method) as well as modern BIOS (that provide both
_CRS and _DSD). Also the use of "cd" appears to be fairly consistent
across other users of this API (other MMC host controller drivers).

Commit c31165d740 ("mmc: sdhci-pci: Add support for HS200 tuning mode
on AMD, eMMC-4.5.1") added a HS200 tuning method for use with AMD SDHCI
controllers. As described in the commit subject, this tuning is specific
for HS200. However, as implemented, this method is used for all host
timings, because platform_execute_tuning, if it exists, is called
unconditionally by sdhci_execute_tuning(). This breaks tuning when using
the AMD controller with, for example, a DDR50 SD card.
Instead, we can implement an amd execute_tuning wrapper callback, and
then conditionally do the HS200 specific tuning for HS200, and otherwise
call back to the standard sdhci_execute_tuning().

Tuning can leave the IP in an active state (Buffer Read Enable bit set)
which prevents the entry to low power states (i.e. S0i3). Data reset will
clear it.
Generally tuning is followed by a data transfer which will anyway sort out
the state, so it is rare that S0i3 is actually prevented.

sdhci_enable_irq_wakeups() is already called by sdhci_suspend_host() so
sdhci-pci should not need to call it. However sdhci_suspend_host() only
calls it if wakeups are enabled, and sdhci-pci does not enable them until
after calling sdhci_suspend_host(). So move the calls to
sdhci_pci_init_wakeup() before calling sdhci_suspend_host(), and
stop calling sdhci_enable_irq_wakeups(). That results in some
simplification because sdhci_pci_suspend_host() and
__sdhci_pci_suspend_host() no longer need to be separate functions.

The MMC_CAP2_HC_ERASE_SZ is used only by a few mmc host drivers. Its intent
is to enable eMMC's high-capacity erase size, as to improve the behaviour
of the erase operations.
We should strive to avoid software configuration options that aren't
necessary, but instead deploy common behaviours. For these reasons, let's
remove the capability bit for MMC_CAP2_HC_ERASE_SZ and make it the default
behaviour.
Note that this change doesn't affect eMMCs supporting trim/discard, because
these commands operates on sectors and takes precedence over erase
commands.
