Mark Brown a850260e47 ASoC: Set idle_bias_off for WM1250 EV1
The WM1250 EV1 is functionally digital in a system (the analogue I/O
is either ground referenced or always powered) so flag it as idle_bias_off.

Mark Brown 213eb0fb1e ASoC: Add platform data for WM1250 EV1 GPIOs
The WM1250 EV1 has some GPIOs which can be used to control the behaviour
at runtime. Request them all if supplied and add a set_bias_level()
function to start and stop the clocks.

Mark Brown 4bb3f43c6e ASoC: Add initial WM1250-EV1 Springbank audio I/O module driver
The WM1250-EV1 Springbank audio I/O module for the Wolfson Glenfarclas
reference platform provides a simple audio I/O with an independant clock
domain, intended to simulate cellular modem and bluetooth subsystems
within the platform.

The card supports some limited GPIO based control but this is currently not
implemented.
