Fix the location of "Setting variable MTRR" printk.
Without that fix the debugging is harder because the person debugging
coreboot will see the following twice(note the repeated MTRR number):
Setting variable MTRR 0, base: 0MB, range: 4096MB, type WB
[...]
Setting variable MTRR 1, base: 4096MB, range: 512MB, type WB
Setting variable MTRR 1, base: 4608MB, range: 256MB, type WB
Setting variable MTRR 1, base: 3072MB, range: 1024MB, type UC
instead of the following twice:
Setting variable MTRR 0, base: 0MB, range: 4096MB, type WB
[...]
Setting variable MTRR 1, base: 3072MB, range: 1024MB, type UC
Thanks to kmalkki on #coreboot's Freenode IRC channel for the idea:
May 25 23:57:17 <kmalkki> I would add (move) that "Setting variable MTRR..." debug at the end of set_var_mtrrs()
