x86: Add a function to set variable MTRRs
Normally U-Boot handles MTRRs through an add/commit process which
overwrites all MTRRs. But in very early boot it is not desirable to clear
the existing MTRRs since they may be in use and it can cause a hang.
Add a new mtrr_set_next_var() function which sets up the next available
MTRR to the required region.
