microcode: add flexability: type & initramfs control
Bug reported that the MICROCODE option did not provide enough
flexability, as it enabled both AMD & Intel options by default, and
placed both sets of microcode into the initramfs.
Existing boolean option MICROCODE is now a string, which takes
no/all/amd/intel as inputs, describing which variant of kernel options
to enable. Boolean inputs are converted to no/all settings. This option
no longer include microcode in initramfs.
New option MICROCODE_INITRAMFS, enabled by default, includes the
microcode for matching kernel config options (INTEL/AMD) into the
initramfs. For users using sys-boot/grub-2.02-r1 or another bootloader
that supports multiple initramfs options, this option can be safely
disabled.
