intel-microcode: fix microcode loading on newer kernels
The /dev/microcode interface and microcode-ctl utility has
been deprecated in favor of the new kernel
/sys/devices/system/cpu/microcode/reload interface as documented in:
https://github.com/torvalds/linux/blob/master/Documentation/x86/microcode.rst
It expects the microcode binaries to be split out and loaded from
/lib/firmware, eg:
/lib/firmware/intel-ucode/06-01-01
/lib/firmware/intel-ucode/06-01-02
/lib/firmware/intel-ucode/06-01-06
/lib/firmware/intel-ucode/06-01-07
/lib/firmware/intel-ucode/06-01-09
...
This change does not affect the earlyfw cpio generated by inte-ucode.
