Add handling for VIDIOC_CREATE_BUFS ioctl in driver.
This ioctl is used to create buffers for memory mapped
or DMA buffer I/O.
It can be used as an alternative or in addition to the
ioctl VIDIOC_REQBUFS ioctl, when a tighter control over
buffers is required.
This ioctl can be called multiple times to create buffers
of different sizes.
Partially Fixes: v4l2-compliance:
test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF.

Add handling for VIDIOC_QUERYBUF ioctl in driver.
This can be used to query the status of a buffer
at any time after buffers have been allocated with
the VIDIOC_REQBUFS ioctl.

- Request api allows to synchronize controls along
with buffers.
- Client allocates a request fd. This request fd is
associated with control and set using s_ext_ctrls.
Such controls are stored by the framework and not
applied immediately.
- Request fd is also associated with input qbuf and
queued to driver. Following this actual request is
queued. Buffers do not enter the queue untill the
request is queued.
- As part of qbuf, driver call request_setup() which
inturn sets the control to driver.

Decoder needs to support VIDIOC_TRY_DECODER_CMD and
Encoder needs to be support VIDIOC_TRY_ENCODER_CMD.
Partially Fixes: V4l2-complience:
testDecoder(VIDIOC_(TRY)_DECODER_CMD) for decoder.
testEncoder(VIDIOC_(TRY)_ENCODER_CMD) for encoder.

- Do not clear V4L2_FL_USES_V4L2_FH flag because this
flag indicates that file->private_data points to
&struct v4l2_fh.
- Initialize v4l2 ctrl handler with driver ctrl handler.
- Add ctrl ops for g_volatile_ctrl to return updated
value of volatile ctrls from driver.
