drm/msm/a2xx: Call adreno_gpu_init() earlier

The adreno_is_a20x() and adreno_is_a225() functions rely on the
GPU revision, but such information is retrieved inside adreno_gpu_init(),
which is called afterwards.

Fix this problem by caling adreno_gpu_init() earlier, so that
the GPU information revision is available when adreno_is_a20x()
and adreno_is_a225() run.

Tested on a imx53-qsb board.
