[PATCH 1/1] drm/amdgpu: remove unnecessary rlc reset function on gfx9

[PATCH 1/1] drm/amdgpu: remove unnecessary rlc reset function on gfx9

[Le Ma]

From: Le Ma <le.ma@amd.com>

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.
