drm/amdgpu/gfx11: update gpu_clock_counter logic

commit d5aa417808cf14c052ca042920b3c6b9f1dc6aa4 upstream.

This code was written prior to previous updates to this
logic for other chips.  The RSC registers are part of
SMUIO which is an always on block so there is no need
to disable gfxoff.  Additionally add the carryover and
preemption checks.

v2: rebase
