The thermal throttling parameters were constant and hardcoded, not allowing
changes for different NIC families.
Change this so that the values are part of the NIC family configuration and
are not constant (so they can be changed dynamically in the future).

The allocation of the DCCM between the data and the stack
can theoretically change without notice to the driver, but
the total size is HW-fixed. Since the stack CCM (runtime
stack) has also data important to the FW - this patch allows
pulling the whole DCCM in one piece and adds it to the dump
data.
If the size isn't known - just use the data part of the
DCCM as it appears in the FW TLVs.

A hardware bug had been discovered on 7260 / 3160 and 7265
and the workaround for this bug is to force the NIC to stay
awake as long as we have host commands in flight. This
workaround has been introduced for all NICs in a previous
patch:
b943949105 ("iwlwifi: pcie: keep the NIC awake when commands are in flight")
In newer NICs, this bug is solved, so we can let the NIC go
to sleep even when we send commands. The hardware will wake
up when we increment the scheduler write pointer.
Make the workaround conditional to only use it on affected
hardware.

1. Enable LP XTAL to avoid HW bug where device may consume much
power if FW is not loaded after device reset. LP XTAL is
disabled by default after device HW reset. Configure device's
"persistence" mode to avoid resetting XTAL again when SHRD_HW_RST
occurs in S3.
2. Add methods to access SHR (shared block memory space) directly from PCI
bus w/o need to power up MAC HW.
Shared internal registers (e.g. SHR_APMG_GP1, SHR_APMG_XTAL_CFG)can be
accessed directly from PCI bus through SHR arbiter even when MAC HW is
powered down. This is possible due to indirect read/write via
HEEP_CTRL_WRD_PCIEX_CTRL (0xEC) and HEEP_CTRL_WRD_PCIEX_DATA (0xF4)
registers.
Use iwl_write32()/iwl_read32() family to access these registers. The MAC HW
need not be powered up so no "grab inc access" is required.
For example, to read from SHR_APMG_GP1 register (0x1DC),
first, write to the control register:
HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register)
HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 2 (read access)
second, read from the data register HEEP_CTRL_WRD_PCIEX_DATA[31:0].
To write the register, first, write to the data register
HEEP_CTRL_WRD_PCIEX_DATA[31:0] and then:
HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register)
HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 3 (write access)

version to 8.

We changed the timeout for the interrupt coealescing for
calibration, but that wasn't effective since we changed
that value back before loading the firmware. Since
calibrations are notification from firmware and not Rx
packets, this doesn't change anyway - the firmware will
fire an interrupt straight away regardless of the interrupt
coalescing value.
Also, a HW issue has been discovered in 7000 devices series.
The work around is to disable the new interrupt coalescing
timeout feature - do this by setting bit 31 in
CSR_INT_COALESCING.
This has been fixed in 7265 which means that we can't rely
on the device family and must have a hint in the iwl_cfg
structure.
