MIPS: Rearrange ENTRYLO field definitions

The generic field definitions (i.e. present before MIPS32/MIPS64) in
mipsregs.h are conventionally not prefixed with MIPS_, so rename the
recently added MIPS_ENTRYLO_* definitions for the G, V, D, and C fields
to ENTRYLO_*. Also rearrange to put the EntryLo and EntryHi definitions
in the right place in the file.

Fixes: 8ab6abcb ("MIPS: mipsregs.h: Add EntryLo bit definitions")
