[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.
