H.J. Lu 4fdd4d41a1 x86: Detect Intel Advanced Matrix Extensions 
Intel Advanced Matrix Extensions (Intel AMX) is a new programming
paradigm consisting of two components: a set of 2-dimensional registers
(tiles) representing sub-arrays from a larger 2-dimensional memory image,
and accelerators able to operate on tiles.  Intel AMX is an extensible
architecture.  New accelerators can be added and the existing accelerator
may be enhanced to provide higher performance.  The initial features are
AMX-BF16, AMX-TILE and AMX-INT8, which are usable only if the operating
system supports both XTILECFG state and XTILEDATA state.

Add AMX-BF16, AMX-TILE and AMX-INT8 support to HAS_CPU_FEATURE and
CPU_FEATURE_USABLE.
