reboot executing.
Before this revision, driver will try to trigger hw after
power domain disable during reboot procedure, and cause a
system halt.

As gpu power on and off frequently, and the interval time is smaller
than the polling time of devfreq, add power-off-delay function to
ensure devfreq work fine.

There are too many NOC clocks and all of them are critical clocks.
This approach is unnecessary, we only remove them and keep them
always enable, and caused by increased power consumption is only
<=3ma.

To simplify the description of the clock for RK3399, we don't need to
add many GRF gates clock nodes and keep them always enable,
In this case, we can avoid some of the operations GRF registers exception
problems, and caused by increased power consumption is only <=1ma.

Rk3399 support single and burst mode, and flushp instruction.
But burst mode improve transfer efficiency.

Because rk3368 pl330 dma controller doesn't support single
mode, so it is necessary to set peripherals-req-type-burst.

Pl330 integrated in rk3368 platform doesn't support
DMAFLUSHP function. So we add arm,pl330-broken-no-flushp quirk
for it.
