drm/msm: Fix the a650 hw_apriv check
Commit 604234f33658 ("drm/msm: Enable expanded apriv support for a650") was checking the result of adreno_is_a650() before the gpu revision got probed in adreno_gpu_init() so it was always coming across as false. Snoop into the revision ID ahead of time to correctly set the hw_apriv flag so that it can be used by msm_gpu to properly setup global buffers.
