Subject: ARM: 9388/2: mm: Type-annotate all per-processor assembly routines

Type tag the remaining per-processor assembly using the CFI
symbol macros, in addition to those that were previously tagged
for cache maintenance calls.

This will be used to finally provide proper C prototypes for
all these calls as well so that CFI can be made to work.
