commit cd1c32ca969ebfd65e61312c988223bb14f09c2e is an early premature
rendition of the patch. Augment it with this delta patch to:
* correctly mark offset and size of the matching bin file
* use __pa instead of __pa_nodebug during AP load
* check for !initrd_start before using it

Add support for parsing through multiple families' microcode patch
container binary files appended together when early loading. This is
already supported on Intel.

Change find_ucode_in_initrd() to __init and only let BSP call it
during cold boot. This is the right thing to do because only BSP will
see initrd loaded by the boot loader. APs will offset into
initrd_start to find the microcode patch binary.

Fix section mismatch warnings on microcode_amd_early.
Compile error occurs when CONFIG_MICROCODE=m, change so that early
loading depends on microcode_core.
