ACPICA: Add more methods eligible for NULL package element removal
This change adds another group of predefined names to the list
of names eligible to have NULL package elements dynamically
removed. This group is the names that return a single
variable-length package containing simple data types such
as integers, buffers, strings. This includes: _ALx,_BCL,_CID,
_DOD,_EDL,_FIX,_PCL,_PLD,_PMD,_PRx,_PSL,_Sx, and _TZD.
