soc/intel/cannonlake: Add child CARD device into eMMC/SD controller
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.
