ACPICA: Fix for resource descriptor optimization issues for _CRS/_SRC
Fixed a problem where resource descriptor size optimization
could cause a problem when a _CRS resource template is passed
to a _SRS method. The _SRS resource template must use the same
descriptors (with the same size) as returned from _CRS. This
change affects the following resource descriptors: IRQ/IRQNoFlags
and StartDependendentFn/StartDependentFnNoPri.
