The GPU 'CONFIG' registers used to work around hardware issues are

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.
