Yes, "sysreg" clock was originally intended to be included in this list,
but this clock is not really specific to the FIMC-IS subsystem so I removed
it from the driver [1]. The biding documentation needs to be updated.
Good catch, thanks.

Oops, I didn't notice it during tests, since this I2C bus controller
is handled by the Cortex A5 firmware. I'll change it to 0x12140000.
