Subrata Banik b53e27bc24 soc/intel/alderlake: Implement API to disable UFS controllers
This patch implements a new API to make the UFS controller function
disabled. Additionally, perform a warm reset post disabling the UFS
controller to let PMC know about the state of the UFS controller
and disable the MPHY clock.

BUG=b:264838335
TEST=Able to build and boot Google/Marasov successfully.
From the AP log, I am able to confirm that UFS is function disabled
using PSF.
