iio: light: ROHM BH1745 colour sensor

Add support for BH1745, which is an I2C colour sensor with red, green,
blue and clear channels. It has a programmable active low interrupt
pin. Interrupt occurs when the signal from the selected interrupt
source channel crosses set interrupt threshold high or low level.

Interrupt source for the device can be configured by enabling the
corresponding event. Interrupt latch is always enabled when setting
up interrupt.

Add myself as the maintainer for this driver in MAINTAINERS.
