The Digital Video Port (DVP, the 16-bit variant) of the RK3568 VICAP
is broken out to the PF5 mainboard expansion header.
Enable it in the device tree overlay for the WolfVision PF5 IO
Expander board.

Habidere,

This patch was skipped when the RK3568 series was applied, as the
MEDIA_PCLK_SAMPLE_DUAL_EDGE definition was introduced in the very same
series.

With the definition mainline for two kernel releases now, it should be
safe to merge this device tree modification.

Thanks in advance!
