media: i2c: ov5647: replace devm_gpiod_get with devm_gpiod_get_optional

Browse Source 
This changed is based on the upstream source code[0].

When devm_gpiod_get is used, the driver may not be probed properly as
'pwdn' gpio may not exist. Therefore, devm_gpiod_get_optional is used
so that the probe will not fail when the 'pwdn' gpio does not exist.
