The SD controller seems to take some time after restarting
the clock at 1.8V before it actually switches from 3.3V to
1.8V. Add a _DSM method that simply sleeps when switching
between 3.3V and 1.8V. Otherwise, the kernel times out too
quickly waiting for the card to acknowledge the 1.8V switch.
The card itself is waiting until it sees the clk signal being
driven at 1.8V.
BUG=b:125441242
TEST=Boot Hatch with SD card and CR2 removed, observe voltage
switch succeeds.

SD controller in CNL-PCH provides a ability to configure the behavior of
SD_VDD1_PWR_EN# as an active high or low signal. FSP provides an UPD
"SdCardPowerEnableActiveHigh" to control the same.
However, for platforms using SD_VDD1_PWR_EN# as active high, the SDXC
card connector is always powered and may impact system power. This is because
SD_VDD1_PWR_EN# does not de-assert during SDXC D3 or when SD card is not
inserted.
Workaround is to change the pad ownership of SD_VDD1_PWR_EN to GPIO and
force the TX buffer to low in _PS3. And restore the pad mode to native
function in _PS0.
Hence add a Kconfig option to update the UPD, which the board can select
based on how the SD_VDD1_PWR_EN is implemented on it. And, the workaround
gets applied based on this config.

Clear EMMC timeout register to avoid EMMC issue according to cannonlake
bios writer guide. _PS0 is not called by kernel when boot source is not
EMMC but kernel still initializes emmc. Add _INI to EMMC,SD asl code to
cover cases that the system doesn't boot from EMMC.

For the internal eMMC to be used by non-chrome for installation,
the CARD device and _RMV methods are required. Without these,
other OSes does not show the eMMC as a valid installation target.
TEST= boot CNL-RVP with Tiano payload and install Windows 10
to the internal eMMC drive.

TEST=Suspend and resume using 'echo freeze > /sys/power/state'.

Two W/A had been added here for EMMC to make it working properly.
1. Enable power gating after D3 entry, disable power gating before D0
entry.
2. Add 50 ms delay to ensure Rcomp calibration done before EMMC out of
D3.
