[media] omap_vout: fix section mismatch

Fix the following warning by using platform_driver_probe() instead of
platform_driver_register():

WARNING: drivers/media/video/omap/omap-vout.o(.data+0x24): Section
mismatch in reference from the variable omap_vout_driver to the function
.init.text:omap_vout_probe()
The variable omap_vout_driver references
the function __init omap_vout_probe()
