[PATCH] x86: correct CPU_AMX_{BF16,INT8}_FLAGS

[Jan Beulich]

AMX-TILE is a prereq to these, as already correctly expressed by
CPU_ANY_AMX_TILE_FLAGS. Express the dependency also in the reverse
("positive") direction.

Ideally we would teach i386-gen to at least check (better derive) such
two-way dependencies.
