Fixes hang while closin
The spi-sun4i driver already has the ability to do large transfers.
However, the max transfer size reported is still fifo depth - 1.
Update the max transfer size reported to the max value possible.

The panel should be enabled after the controller so that we do not have
visual glitches on the panel while the controller is setup. Similarly,
the panel should be disabled before the controller.

I had some issues where setting the brightness for pwm-backlight to 0
was not turning off the backlight sometimes.
This patch fixes the issue for me. Thanks.

If the enable-gpios property of a simple panel in device tree is set,
the GPIO is not toggled on/off because of missing calls to
