[ Upstream commit db07ce5da8b26bfeaf437a676ae49bd3bb1eace6 ]
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.
