soc/intel/alderlake: Add support for UFS controller

UFS(Universal Flash Storage) is the next generation storage standard and
a SCSI storage technology. It is also a successor of eMMC.

Following changes are needed to add support for UFS -
1) Add UFS controller to chipset.cb and keep it off by default
2) Hook up FSP enable UPD for UFS #1 to the device from chipset.cb
