media: vimc: sensor: Add pixel_rate,vblank and hblank configuration

Browse source

pixel_rate and hblank as read only parameter. vblank can be configured
to match the desired frame rate.

Default values are, pixel_rate - 160 MHz, hblank - 800.
vblank defaults to an equivalent value of 30 fps for resolutions less than
or equal to 1920x1080 and 10 fps for higher resolutions. For higher
resolutions, modify pixel_rate in the driver code.
fps = pixel_rate / ((width + hblank) * (height + vblank))
minimum vblank - 4, maximum vblank - 65535

The configured fps delay is pre-calculated into jiffies and
stored in the sensor's hw structure for efficient access by the
streamer thread.
