From: Mark Brown <broonie@xxxxxxxxxx>
Rather than requiring each board to explicitly disable the I2S controllers
it is not using instead require boards to enable those that they are using.
This is required for audio operation on Arndale, one of the unused I2S
controllers is pinmuxed with the LDO enable GPIOs for the WM1811A.
