Hello,
This is v2 of the rkvdec driver which was initially posted as part of
my RFC adding codec helpers.
For this version, I decided to get rid of the helper stuff which is
likely to take some more time to settle. The patchset now contains a
proper DT binding doc.

RK3399 has a Video decoder, define the node in the dtsi. We also add
the missing power-domain in mmu node and enable the block.

The rockchip vdec block is a stateless decoder that's able to decode
H264, HEVC and VP9 content. This patch only adds H264 support and is
making use of the m2m codec helpers.

These helpers are used by stateless codecs when they support multiple
slices per frame and hold capture buffer flag is set. It's expected that
all such codecs will use this code.

This patch adds support for the V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF flag.
It also adds a new V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF capability.
Drivers should set vb2_queue->subsystem_flags to
VB2_V4L2_FL_SUPPORTS_M2M_HOLD_CAPTURE_BUF to indicate support for this flag.

Currently the "chip found" message is shown even in the case where the
I2C address is wrongly passed in the device tree, or also in the case of
probe failure, which is misleading.
To avoid such problem, move this message after real I2C transactions
