Steven Price 3e0685315f drm/panfrost: Ensure GPU quirks are always initialised
[ Upstream commit 8c3c818c23a5bbce6ff180dd2ee04415241df77c ]

The GPU 'CONFIG' registers used to work around hardware issues are
cleared on reset so need to be programmed every time the GPU is reset.
However panfrost_device_reset() failed to do this.

To avoid this in future instead move the call to
panfrost_gpu_init_quirks() to panfrost_gpu_power_on() so that the
regsiters are always programmed just before the cores are powered.
