Define default address via Kconfig. There is no need to change this address
for most of the boards but it is also possible. This one line save a lot of
lines in defconfigs that's why make sense to do it.

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.
