soc/intel/cmn/acpi: Use Kconfig guards for UFS workarounds

This change introduces Kconfig guards around the UFS workaround code
in the common ACPI ASL file. This ensures that these workarounds are
only applied when necessary, allowing future SoCs with UFS controllers
to reuse the common ASL file without modification.

By using Kconfig, we can enable or disable the workarounds based on
the specific SoC configuration, providing greater flexibility and
maintainability.

BUG=b:379828045
TEST=Able to compile google/fatcat.
