media: dw100: Implement V4L2 requests support
The dw100 dewarper hardware present on the NXP i.MX8MP allows very
flexible dewarping using a freely configurable vertex map. Aside from
lens dewarping the vertex map can be used to implement things like
arbitrary zoom, pan and rotation. The current driver supports setting
that vertex map before calling VIDIOC_STREAMON.
To control above mentioned features during streaming it is necessary to
update the vertex map dynamically. To do that in a race free manner V4L2
requests support is required. Add V4L2 requests support to prepare for
dynamic vertex map updates.
