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.
