  This series fixes the power-up sequence delays to support some 15-pin 
FFC compatible OV5640 modules.

Without appropriate delays after both gpio and register-based powerdown 
and reset the sensor SCCB was not very stable, and probe would sometimes 
fail at check_chip_id.

Changes in v3:
- Move register-based reset to the common powerup_sequence function
- Only add 5ms delay for PWUP not for PWDN in ov5640_set_stream_dvp

v2: https://lore.kernel.org/all/20221219143056.4070-1-j-luthra@ti.com/
