Carl-Daniel Hailfinger e4d46b9e90 early_mtrr_init() nukes all MTRRs including those which we use for CAR. 
That means if it ever gets called while CAR is active, our stack will be
dropped and mayhem will ensue.
Besides that, it just replicated stage0.S functionality which already
nukes all MTRRs before enabling CAR.

We could move XIP ROM caching from stage0.S to early_mtrr_init(). It
would probably slow down booting a bit, but the amount of asm code would
be reduced.

Thanks to Corey for telling me that early_mtrr_init() broke booting for
him.
