ACPI: thermal: Drop nocrt parameter

ACPI: thermal: Drop nocrt parameter

The `nocrt` module parameter has no code associated with it and does
nothing.  As `crt=-1` has same functionality as what nocrt should be
doing drop `nocrt` and associated documentation.

This should fix a quirk for Gigabyte GA-7ZX that used `nocrt` and
thus didn't function properly.
