media: ov5640: change the period of pixel clock for VGA resolution
This patch changes the period of pixel clock for VGA to 0x44.
We need to change the value for VGA resolution since the global
init table sets the value as 0x0a which is not applicable to
the VGA resolution.
Note that the value has to be determined depending on the value
of the MIPI clock rate.
