Always initialize the UPA target module id in the interrupt mapping

Browse Source 
register to the one of the processor doing the interrupt setup. This
is required since this field is preinitialized to 0, but there exist
machines which have no processor with a MID of 0 (e.g. e450s with 1 or 2
processors).

Add some more macros for handle the interrupt mapping registers, and
rename some existing ones for consistency.
