This patch the I2C board information for the WM8994 used in the Goni/Aquila
as audio codec and adds the I2C/I2S platform drivers. Additionlly, to
control power consumption have registerd the voltage consumer of WM8994
to the regulator framework.
Additionally, I explain the constraints of the regulator of WM8994 codec.
All these consumer supply of WM8994 codec connected the regulator(VCC_1.8V)
on a circuit diagram. "VCC_1.8V" regulator is always enabled, because it is
used to many devices on Goni/Aquila board. This is required especially
when there are many devices physically attached to "VCC_1.8V" and some of
they did not "register" as consumers to "VCC_1.8V". "VCC_1.8V" might be
turned off by those who are registered while "unregistered" are still active.
