drm/amdgpu: fix JPEG v4.0.5 queue reset failure in DPG mode
Like jpeg_v5_0_0, in DPG mode the ring reset path only clears the
JPEG_PG_MODE bit and never resets a hung JRBC, so the post-reset ring test
times out and the driver falls back to a full MODE1 reset.
Temporarily force the static power-gating path during the reset so the
stop/start sequence power-cycles the JPEG block (JMI soft reset + power
off/on), matching the jpeg_v4_0 reset.
