Consolidate the whole logic which determines whether the microcode loader
should be enabled or not into a single function and call it everywhere.
Well, almost everywhere - not in mk_early_pgtbl_32() because there the kernel
is running without paging enabled and checking dis_ucode_ldr et al would
require physical addresses and uglification of the code.
But since this is 32-bit, the easier thing to do is to simply map the initrd
unconditionally especially since that mapping is getting removed later anyway
by zap_early_initrd_mapping() and avoid the uglification.
In doing so, address the issue of old 486er machines without CPUID
support, not booting current kernels.
