[PATCH] ASoC: madera: Add dependencies on MFD

[Charles Keepax]

The Madera CODECs use regmap_irq functions but nothing ensures that
regmap_irq is built into the kernel. Add dependencies on the ASoC
symbols for the relevant MFD component. There is no point in building
the ASoC driver if the MFD doesn't support it and the MFD part contains
the necessary dependencies to ensure everything is built into the
kernel.
