drm/msm/adreno: set cx_misc_mmio regardless of if platform has LLCC

Browse source

Platforms without a LLCC (e.g. milos) still need to be able to read and
write to the cx_mem region. Previously if LLCC slices were unavailable
the cx_misc_mmio mapping was overwritten with ERR_PTR, causing a crash
when the GMU later accessed cx_mem.

Move the cx_misc_mmio mapping out of a6xx_llc_slices_init() into
a6xx_gpu_init() so that cx_mem mapping is independent of LLCC.
