[PATCH v2 5/8] v4l: Switch from V4L2 OF not V4L2 fwnode API

[Sakari Ailus <sakari.ailus@linux.intel.com>]

Switch users of the v4l2_of_ APIs to the more generic v4l2_fwnode_ APIs.

Existing OF matching continues to be supported. omap3isp and smiapp
drivers are converted to fwnode matching as well.

Acked-by: Benoit Parrot <bparrot@ti.com> # i2c/ov2569.c, am437x/am437x-vpfe.c and ti-vpe/cal.c
