request_threaded_irq() rejects calls which both do not specify a handler
(indicating that the primary IRQ handler should be used) and do not set
IRQF_ONESHOT because the combination is unsafe with level-triggered
interrupts.  It is safe in this case, though, since max98090 IRQs are
edge-triggered and the interrupts aren't ACK'ed until the codec's IRQ
status register is read.  Because of this, an IRQF_ONESHOT interrupt
doesn't really make a difference, but request one anyway in order to make
request_threaded_irq() happy.

The max98090 driver currently treats the digital mic enable as a supply
on the record path, causing the digital mic enable to always be turned on
when attempting to record.  This is incorrect, however, since the digital
mic enable is also a mux control where 0 selects the ADC output as input
to the record-path DSP and 1 selects the digital mic.  This patch adds
a virtual DMIC mux to the reocrd path so that we can switch between the
ADC and the digital mic for recording.
