Yuan Liu 6fd397e82b HV: Add CLFLUSHOPT instruction. ...

CLFLUSHOPT is used to invalidate from every level of the cache hierarchy
in the cache coherence domain the cache line that contains the linear
address specified with memory operand. If that cache line contains
modified date at any level of the cache hierarchy, that data is written
back to memory.

If the platform does not support CLFLUSHOPT instruction, boot will fail.
