Ashok Raj 91df9fdf51 x86/microcode/intel: Writeback and invalidate caches before updating microcode 
Updating microcode is less error prone when caches have been flushed and
depending on what exactly the microcode is updating. For example, some
of the issues around certain Broadwell parts can be addressed by doing a
full cache flush.

[ Borislav: Massage it and use native_wbinvd() in both cases. ]
