soc/intel/skylake: fix eMMC visibility under Windows
For the internal eMMC to be used by Windows for installation, an ACPI device for the card/drive is required, with _RMV indicating that the device is non-removable. Add the required device/method to allow Windows to "see" the internal eMMC.
TEST: boot google/chell with Tianocore payload and install Windows 10 to the internal eMMC drive.
