intel microcode: split up microcode loading stages
This patch only applies to CONFIG_MICROCODE_IN_CBFS. The intel microcode update routine would always walk the CBFS for the microcode file. Then it would loop through the whole file looking for a match then load the microcode. This process was maintained for intel_update_microcode_from_cbfs(), however 2 new functions were exported: 1. const void *intel_microcode_find(void) 2. void intel_microcode_load_unlocked(const void *microcode_patch) The first locates a matching microcode while the second loads that mircocode. These new functions can then be used to cache the found microcode blob w/o having to re-walk the CBFS. Booted baskingridge board to Linux and noted that all microcode revisions match on all the CPUs.
