The media_ldb_root_clk supply LDB serializer. These clock are usually
shared with the LCDIFv3 pixel clock and supplied by the Video PLL on
i.MX8MP, but the LDB clock run at either x7 or x14 rate of the LCDIFv3
pixel clock. Allow the LDB to reconfigure Video PLL as needed, as that
results in accurate serializer clock.
