media: ov5640: Fix soft reset sequence and timings

Browse source

Move the register-based reset out of the init_setting[] and into the
powerup_sequence function. The sensor is power cycled and reset using
the gpio pins so the soft reset is not always necessary.

This also ensures that soft reset honors the timing sequence
from the datasheet [1].
