Introduces the V4L2 video interface and feature management for the
MediaTek ISP7x CAMSYS. These interfaces include various functionalities,
such as video operation initialization and registration. They also
manage MediaTek-specific formats and handle buffers for MediaTek camera
video devices. This integrates CAMSYS functionalities to be compatible
with the V4L2 framework.

Why V4L2_BUF_TYPE_META_OUTPUT use different timestamp flag?
Different output data is generate at the same time,
so use the same timestamp so we are able to link these output data to the same frame.
And I could not find anywhere to define V4L2_BUF_FLAG_TIMESTAMP_BOOTIME.
So drop V4L2_BUF_FLAG_TIMESTAMP_BOOTIME and use V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC for all queue.

V4L2_PIX_FMT_PISP_COMP1_RGGB is a Raspberry Pi format, and its fmtdesc is filled in v4l_fill_fmtdesc().
So move these fill code into v4l_fill_fmtdesc().
