ASoC: tas*: Fix up GPIO usage

Merge series from Linus Walleij <linus.walleij@linaro.org>:

The TI TAS drivers use some legacy GPIO code and headers,
this series fixes it up.

The TAS2781 is a special case since it adds a handful of
lines of deviating code to reconfigure a GPIO line for
IRQ mode and then never actually use the IRQ obtained in
the code. Is the line used by autonomous hardware? I'm
puzzled by this.

Anyways the patch suggest how to solve this properly by
fixing the parent irqchip and I'm happy to help.
