Subject: [PATCH 1714/2940] drm/amdgpu: remove unnecessary rlc reset function
on gfx9
The rlc reset function is not necessary during gfx9 initialization/resume phase.
And this function would even cause rlc fw loading failed on some gfx9 ASIC.
Remove this function safely with verification well on Vega/Raven platform.
