Jeff Kletsky 736d16baad ath79: GL-AR300M series: Add I2C Support 
The GL-AR300M series have an internal header for I2C.

Provide DTS definitions for the i2c-gpio driver.

The I2C drivers; kmod-i2c-core, kmod-i2c-gpio
consume ~20 kB of flash and can be loaded as modules,

Default clock measured ~11.4 ms period, ~88 kHz

The board has two sets of (unpopulated) headers.  While facing the
back of the board (looking into the Ethernet jacks), and looking from
the top, the one on the left edge of the baord with four holes is the
I2C header. It appears to be labeled J8 on "GL-AR300M-V1.4.0" boards.
