Currently GuCRC is disabled in suspend path for xe.
Rc6 is a prerequiste to enable s0ix and
should not be disabled for s2idle. There is no requirement
to disable GuCRC for S3+.

Remove it from xe_guc_pc_stop, thus removing from suspend path.
Retain the call in other places where xe_guc_pc_stop is
called.

v2: add description and return statement to kernel-doc (Rodrigo)
v3: update commit message (Rodrigo)
v4: add mem_access_get to the gucrc disable function
