There isn't actually a a690_gmu.bin. But it appears that the normal
a660_gmu.bin works fine. Normally all the devices within a sub-
generation (or "family") will use the same fw, and a690 is in the a660
family.

holding devfreq locks. But in the teardown path, we were calling
dev_pm_domain_detach() while already holding the GMU lock, resulting in
this lockdep splat:

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.

dpu_encoder_phys_wb_wait_for_commit_done expects the IRQ index rather
than the IRQ index in phys_enc->intr table, however writeback got the
older invocation in place. This was unnoticed for several releases, but
now it's time to fix it.
