amd_imc.c: Cleanup C89ism and redundant NULL check

A bit of spring cleaning here to freshen up some C89ism's,
drop a redundant NULLality check in a static local function
and canonicalise branch predictions. Also const correct some
static locals and add missing include while here.

This makes the code overall shorter, more consistent and
succinct.
