Subject: [PATCH 04/10] ASoC: imx: Don't use {en,dis}able_fiq() calls

The driver uses platform-specific mxc_set_irq_fiq() with the VIRQ cookie
passed to it, so it's pretty clear that the driver is absolutely sure
that the FIQ is routed via platform-specific IC, and that the cookie can
be used to mask/unmask FIQs. So, let's switch to the genirq routines,
since we're about to remove FIQ-specific variants.
