This configures GPIO_177 as an input pin for SDCARD card

Linux kernel expects that power management with ACPI should always be
handled using PowerResource. However, some kernel drivers (e.g. ELAN
touchscreen) check to see if reset gpio is passed in by the BIOS to
decide whether the device loses power in suspend. Thus, until the kernel
has a better way for drivers to query if device lost power in suspend,
we need to allow passing in of GPIOs via _CRS as well as exporting
PowerResource to control power to the device.
Update mainboards to export reset GPIO as well as PowerResource for
ELAN touchscreen device.

Maxim98357a speaker amp requires BCLK & SFRM to be active
and stable before it is unmuted. If there is a BLCK and no

sdmode_delay property already exists which facilitates this
configuration. This patch updates "sdmode_delay" to avoid
pop sound.

Snappy is using APL SoC SKU's with 6W TDP max. As Reef,
the energy calculation is wrong with the current VR solution.
Experiments show that SoC TDP max (6W) can be reached
when RAPL PL1 is set to 12W.
Therefore, we've inserted 12W override after reading the fused value (6W)
so that the system can reach the right performance level.
