soc/intel/alderlake: Fix UFS OCP fabric timeout
The delayed return of certain fetch instruction from memory to
the UFS causes the OCP fabric to timeout on the transaction
and become non-responsive.
As recommended by the SoC and IP teams,program the
OCP fabric register to avoid the timeout in the OCP fabric.
This patch adds the following changes
1. Program the OCP fabric registers in the PS0 routine.
2. Move the ssdt contents of UFS to dsdt asl code to avoid
duplication of UFS device creation
BUG=b:240222922
TEST=Build and boot Nirwen UFS board, observe no system hang
during Chrome PLT test.
