Add a Features bullet and an "i2c" configuration section to the
RTL8730E EVB board page describing I2C0-2 as /dev/i2c0-2, the pads the
board table registers and the i2ctool scan command, following the
pke8721daf board format.
Note the two pad constraints that are specific to this chip: a pad
reaches exactly one I2C controller (unlike the GPIO and UART
crossbars), and the pads inside the analogue audio ranges are driven by
the codec and cannot carry I2C.
