On legacy platforms, KCR HW enabling is done at the time the mei
component interface is bound. It's also disabled during unbind.
However, for MTL onwards, we don't depend on a tee component
to start sending GSC-CS firmware messages.

Thus, immediately enable (or disable) KCR HW on PXP's init,
fini and resume.
