media: i2c: ov5645: Fix power sequence
This is mostly a port of Jacopo's fix: commit aa4bb8b8838ffcc776a79f49a4d7476b82405349 Author: Jacopo Mondi <jacopo@jmondi.org> Date: Fri Jul 6 05:51:52 2018 -0400 media: ov5640: Re-work MIPI startup sequence In the OV5645 case, the changes are: - At set_power(1) time power up MIPI Tx/Rx and set data and clock lanes in LP11 during 'sleep' and 'idle' with MIPI clock in non-continuous mode. - At set_power(0) time power down MIPI Tx/Rx (in addition to the current power down of regulators and clock gating). - At s_stream time enable/disable the MIPI interface output. With this commit the sensor is able to enter LP-11 mode during power up, as expected by some CSI-2 controllers. Many thanks to Fabio Estevam for his help debugging this issue.
