Subject[tip:x86/cleanups] x86/mtrr: Rename main.c to mtrr.c and remove duplicate prefixes

x86/mtrr: Rename main.c to mtrr.c and remove duplicate prefixes

Kbuild uses the first file as the name for KBUILD_MODNAME.
mtrr uses main.c as its first file, so rename that file to mtrr.c
and fixup the Makefile.

Remove the now duplicate "mtrr: " prefixes from the logging calls.
