moved hispi lanes phases adjustment to from mt9f002_pgm_initsensor to mt9f002_pgm_detectsensor - this supposedly removed rare i2c write errors

* When power is applied - the sensor enters a low-power standby. Exit from which is
* controlled by the later of 2 events:
* - negation of the RESET_BAR
* - a timeout of the internal power-on reset circuit
*
* There's no need to assert/deassert RESET_BAR but we hold it asserted then deassert.

* The sensor is supposed to leave the hardware standby state and perform some initialization
* sequence that takes T_is = 2700 EXTCLK (MT9F002_EXT_CLK):
* - for 1.6MHz T_is = 1.6 ms
* - for 24.444MHz T_is = 110 us
*
* While doing initialization sensor is unresponsive to i2c.
*
* After init it enters a low-power software standby and enables Voltage-Controlled Oscillator (VCO).
* And internal delay will keep PLL disconneced for up to 1ms so that PLL can lock.
* VCO lock time is 200 us (typical) - 1000 us (max)
