Subject: [PATCH][V2] drm/msm/a5xx: remove null pointer check on pdev

The call chain on a5xx_gpu_init is such that pdev is not going to be
null, so the null check on pdev can be removed. This also cleans up
a static analysis warning where pdev is dereferenced before the null
check which cannot actually occur.
