On MTL, the HuC is only supported on the media GT, so our validation

[drm] GT0: Incompatible option enable_guc=3 - HuC is not supported!
This can be confusing to the user and make them think that something is
wrong when it isn't, so we need to silence it.
Given that any platform that supports HuC also supports GuC, if a user
tries to enable HuC on a platform that really doesn't support it they'll
already see a message about GuC not being supported, so instead of just
silencing the HuC message on newer platforms we can just get rid of it
entirely.
Not following this argument. Someone might attempt to enable HuC only
and do so on a older platform that supports neither HuC nor GuC. There
would be no GuC warning because GuC was not requested. But now there
would also be no HuC warning either.
