media: ov5640: Rework CSI-2 clock tree

Re-work the ov5640_set_mipi_pclk() function to calculate the
PLL configuration using the pixel_rate and link_freq values set at
s_fmt time.

Rework the DVP clock mode settings to calculate the pixel clock
internally and remove the assumption on the 16bpp format.

Tested in MIPI CSI-2 mode with 1 and 2 data lanes with:
- all the sensor supported resolutions in UYVY, RGB565 and MJPEG formats.
- resolutions >= 1280x720 in RAW Bayer format.
- resolutions < 1280x720 in RGB888 format.
