[media] cx23885[v4]: Fix interrupt storm when enabling IR receiver
Apparently the Flatiron genereates an interrupt after the built-in self
test for each of its left and right channels has completed.
Apparently Conexant wire-OR'ed the Flatiron's interrupt output with the
interrupt output of the CX23885 A/V core.
Those interrupts need to be handled, otherwise, they generate an
interrrupt request storm.
So:
- Add flatiron readreg and writereg functions prototypes
on a new header file;
- Modify the av interrupt handler to cleanup flatiron IRQs if no other
interrupt handling happens.
