drm/i915/guc: write wopcm related register once during uc init
The wopcm registers are write-once, so any write after the first one will just be ignored. The registers survive a GPU reset but not always a suspend/resume cycle, so to keep things simple keep the writes in the intel_uc_init_hw function instead of moving it earlier to make sure we attempt them every time we try to load GuC.
