Negating ADAU1977_BLOCK_POWER_SAI_LDO_EN creates an unsigned long constant
with all bits set which on 64 bit architectures needs to be truncated to
an unsigned int, generating a warning. Add an explicit cast since we know
this is OK.

Both the snd_soc_codec and snd_soc_platform struct do have a pointer to the
parent card and both handle this pointer in mostly the same way. This patch
moves the card field to the component level which will allow further code
consolidation between platforms and CODECS.
Since there are only a handful of users of the snd_soc_codec struct's card field
(and none of the snd_soc_platform's) these are update in this patch as well,
which allows it to be removed from the snd_soc_codec struct.

This problem is well explained by Russell King:
"The sgtl5000 uses a two-stage initialisation process. The first stage
is when the platform driver is probed, where some resources are found
and initialised. The second stage is via the codec driver's probe
function, where regulators are found and initialised using the managed
resource support.
The problem here is that this works fine until the codec driver is
unbound. When this occurs, sgtl5000_remove() is called which is a no-op
as far as the managed resource code is concerned. The regulators remain
allocated, and their pointers in sgtl5000_priv remain valid.
If the codec is now re-probed, it will again try and find the regulators,
which will now be busy. This will fail.
That's not the only problem - if using the LDO regulator, the regulator
is unregistered from the regulator core code, but it still has a user.
When the user is cleaned up (eg, by removing the module) it hits the
free'd regulator, and this can oops the kernel.
This bug was originally introduced by 63e54cd9ca ("ASoC: sgtl5000:
Use devm_regulator_bulk_get()")."
This reverts commit 63e54cd9ca.
Tested on a imx53-qsb board.

This patch adds Realtek ALC286 codec driver.
ALC286 is a dual mode codec, which can run as HD-A or I2S mode.
It is controlled by HD-A verb commands via I2C protocol.
The following is the I/O difference between ALC286 and general I2S codecs.
1. A HD-A verb command contains three parts, NID, VID, and PID.
And an I2S command contains only two parts: address and data.
2. Not only the register address is written, but the read command also
includes the entire write command.
3. rt286 uses different registers for read and write the same bits.
We map verb command to regmap structure. However, we read most registers from
cache to prevent the asymmetry read/write issue in rt286.
