target/arm: Replace sentinels with ARRAY_SIZE in cpregs.h

Browse source 
Remove a possible source of error by removing REGINFO_SENTINEL
and using ARRAY_SIZE (convinently hidden inside a macro) to
find the end of the set of regs being registered or modified.

The space saved by not having the extra array element reduces
the executable's .data.rel.ro section by about 9k.
