Boris Ostrovsky 2b4c91569a x86/microcode/AMD: Use native_cpuid() in load_ucode_amd_bsp()
When CONFIG_PARAVIRT is selected, cpuid() becomes a call. Since
for 32-bit kernels load_ucode_amd_bsp() is executed before paging
is enabled the call cannot be completed (as kernel virtual addresses
are not reachable yet).

Use native_cpuid() instead which is an asm wrapper for the CPUID
instruction.
