ramips: add AW9523 I2C GPIO expander driver

Browse Source

This adds a driver for the AW9523 I2C GPIO expander.

This driver is required to make LEDs as well as buttons on the Tenbay
T-MB5EU-V01 work.

This driver already had several upstream iterations. I'm working to
push this driver to mainline.
