soc/intel/{adl,cmn}: Add/Remove LTR disqualification for UFS
a) Add LTR disqualification in D3 to ensure PMC ignores LTR
from UFS IP as it is infinite.
b) Remove LTR disqualification in _PS0 to ensure PMC stops
ignoring LTR from UFS IP during D3 exit.
c) Add Kconfig (SOC_INTEL_UFS_LTR_DISQUALIFY) check to apply
this LTR WA.
