b8a083ea32 gpio: Merge TCA6416 & TCA6408 drivers into TCA64XX
This merges TCA6416, TCA6408 drivers and adds PCA9555 support.
They handle 8 pin and 16 pin ICs with basic INPUT/OUTPUT functionality.
The register map is fairly similar so there is no point in having two
separate drivers.

7187ccccdc Add TCA6416 GPIO expander support.
Add basic TCA6416 GPIO expander support over I2C bus. The driver handles
enabling and disabling pins, setting pin mode to IN and OUT and
toggling the pins. External interrupts are not supported.
