For rockchip platforms, the userspace uvc application use
bytesused == 0 as a way to indicate that the data is all
zero and unused. In that case, the uvc driver should use
the allow_zero_bytesused flag to keep bytesused 0 rather
than use the buf actual size instead. This can help to
preview 1080P@MJPG faster.

in rk3399 rkvdec, after 264 task run, 264 hardware may remain state,
and it cannot clear completely. Case this, when last task is 264
and current is vp9, vp9 affect decode error. Thus, it should reset
hardware before task run, when 264 switch vp9.

Otherwise we would get the following warning:

Some CPUs can speculate past an ERET instruction and potentially perform
speculative accesses to memory before processing the exception return.
Since the register state is often controlled by a lower privilege level
at the point of an ERET, this could potentially be used as part of a
side-channel attack.
This patch emits an SB sequence after each ERET so that speculation is
held up on exception return.

CMA alloc may failure due to page busy caused by isolated failure,
it's helpful to dump page owner stack for debug.
To use this debug, there should enable PAGE_OWNER debug first by
- CONFIG_PAGE_OWNER=y
- add “page_owner=on” to boot cmdline
then it will shows as following:

Phy internal registers is read by APB bus. If you get phy registers
and APB data at the same time, you will get wrong data which is the
previous value of register. Therefore, pready_cnt must be set bigger
than rden_cnt.
