Generate an 'EMMC' ACPI device under the PCIe root port to which the
GL9763E is attached. The EMMC device contains a child CARD device whose
_RMV method returns 0. This allows Windows to identify the eMMC as a
fixed internal drive instead of a removable one.
This fixes an issue where the Windows 11 installer fails around 55%
with a generic 'Windows 11 installation has failed' error. Install
logs show the failure is due to Windows identifying the storage
device as removable and aborting (error 0xC1420134).
TEST=build/boot Win11 installer on google/taeko with eMMC installed,
verify Windows installer identifies it as a non-removable drive via
diskpart, and install completes successfully.
