x86: mtrr fix debug boot parameter
while looking at:
http://bugzilla.kernel.org/show_bug.cgi?id=11541
I realized that the mtrr.show param cannot work, because
the code is processed much too early.
This patch:
- Declares mtrr.show as early_param
- Stays consistent with the previous param (which I doubt
that it ever worked), so mtrr.show=1 would still work
- Declares mtrr_show as initdata
