  x86, microcode, AMD: Fix early microcode loading (2013-08-12 18:32:45 +0200)

----------------------------------------------------------------
Those are basically two fixes which correct the AMD early ucode loader
from accessing cpu_data too early, i.e. before smp_store_cpu_info()
has copied the boot_cpu_data ontop and overwritten an already empty
structure (which we shouldn't access that early in the first place
anyway).

The second patch is kinda largish for that late in the game but it
shouldn't be problematic because we're simply switching from using
cpu_data to use the CPU family number directly and thus again, not use
uninitialized cpu_data structure.
