x86/ucode: fix for AMD Fam15 CPUs
Remove hardcoded maximum size a microcode patch can have. This is
dynamic now.
The microcode patch for family15h can be larger than 2048 bytes and
gets silently truncated.

Backport from xen-unstable changeset 24411:ca5f588bd203 to Xen 4.1
Could this fix my xen boot problem on athlon x2 (fam 15 according to
cpuinfo)
See xen-devel post:
[Xen-devel] [Xen-users] Problem booting xen 4.1.2 on Athlon 64 X2

Probably not. cpuinfo reports family in decimal. So your Athlon is
Family 0xF; but Christoph's patch is for Family 0x15. For a quick
verification, you can rename your AMD ucode (in
/lib/firmware/amd-ucode) to prevent it from being loaded.
