I2C detection
MINISASTOCSI camera chip is connected via I2C3. The most important address for correct detection is 0x3c.

MINISASTOCSI camera can be also connected to I2C2 interface by moving 0R resistors. However second camera connected on CSI-2 interface have same address 0x3c as MINISASTOCSI camera connected on CSI-1 interface.
