This is a huge, chaotic mass of registers copied over as-is without any
real cleanup.  We'll come back and organize these better, align on
consistent coding style, remove dead code, etc. in separate patches

v2:
 - Add missing include in intel_pxp_irq.c
v3:
 - Correct a few indentation errors (Lucas)
 - Minor conflict resolution
