[PATCH] ASoC: rt5640: Handle nested IRQs

[Sheetal]

From: Anupama Kunkulagunta <akunkulagunt@xxxxxxxxxx>

On some Tegra platforms, the RT5640 codec interrupt line
is connected via a GPIO controller that operates as a
nested IRQ domain. Since nested IRQ controllers only
support threaded handlers, request_irq() returns -EINVAL:

 rt5640 3-001c: Failed to request IRQ 186: -22

Switch to request_any_context_irq() to let the kernel
pick the appropriate handler type based on the parent
IRQ controller.
