media: ov772x: use generic names for reset and powerdown gpios

The ov772x driver uses "rstb-gpios" and "pwdn-gpios" for reset and
powerdown pins.  However, using generic names for these gpios is
preferred.  ("reset-gpios" and "powerdown-gpios" respectively)

There is only one mainline user for these gpios, so rename to generic
names.
