Remove extraneous assigned-clock* from media/i2c/* schemas. assigned-clock and assigned-clock-parent assume that there is a clock that can be assigned and/or a clock parent that similarly can be assigned by firmware which may not always be the case. The sensor properties themselves should not mandate assigned-clock* as a result.

OV9282 sensor is an OmniVision black & white CMOS active pixel digital image
|
|
sensor with an active array size of 1296H x 816V. It is programmable through
|
|
I2C interface. The I2C client address is fixed to 0x60/0x70 as per sensor data
|
|
sheet. Image data is sent through MIPI CSI-2.
|
|
OV9281 has a different lens chief ray angle.
