1. Because of hw problems before, there will be problems with
high-frequency reset. So the frequency must be reduced before reset.
But this operation is unnecessary for now.
2. Iep share clk with rga on rk356x, so frequency reduction may affect rga.

Rootcause:
When hw detect there are more than eight rolling subtitles, it will
trigger a osd max irq but it still running, and that interruption make
the software takes for frame done and disable the clock gate, finally hw
hang when it access the bus.
Solution:
Ignore OSD MAX irq, clean and wait for frame done.

After power lost, spinand may work in a unkonw state and result in
bit flip, including:
1.Write to cache invalid and dirty cache data write to page's array
which result in node CRC error for some pages.
2.One page write fail but the next page write success result in
empty space corruption.

This patch sets the bvalid and id filter time to 10ms for rk356x
USB 2.0 PHY0 which is used for OTG. The filter count is base on
the USB 2.0 PHY GRF pclk 100MHz.
With this patch, it can avoid trigger the bvalid rising edge irq
when unplug the OTG cable.

in rk3328, avsd and vdpu share the same interrupt number,
so, when each one hardware done, avsd and vdpu irq will response.
