Revert "soc/intel/skylake: Clean up SoC ASL code."

This partially reverts commit a7b97510ae.

For the internal eMMC to be used by Windows for installation,
the CARD device and _RMV methods are required.  Without them,
Windows does not see/show the eMMC as a valid installation
target.

TEST: boot google/chell with Tianocore payload and install
Windows 10 to the internal eMMC drive.
