mvtwsi: convert to CONFIG_SYS_I2C framework

Note this has only been tested on Allwinner sunxi devices (support for which
gets introduced by a later patch).

The kirkwood changes have been compile tested using the wireless_space board
config, the orion5x changes have been compile tested using the edminiv2 board
config.
