The OmniVision OG0VA1B is a monochrome image sensor closely related to
the OG0VE1B. It shares the SCCB control interface, power supplies and
the single-lane MIPI D-PHY description, and differs in its chip id, the
test pattern register, the register programming and the output format
(10-bit RAW instead of 8-bit).

Add an og0ve1b_sensor_data entry describing the OG0VA1B together with
its 640x480 60fps register sequence.

Please keep the list alphabetically sorted, also it's fine if
"OG0VE1B_REG_CHIP_ID" is reduced to "OG0V_REG_CHIP_ID".


ACK.
