media: imx-pxp: include linux/interrupt.h

The newly added driver fails to build in some configurations due to a
missing header inclusion:

drivers/media/platform/imx-pxp.c:988:8: error: unknown type name 'irqreturn_t'
 static irqreturn_t pxp_irq_handler(int irq, void *dev_id)
        ^~~~~~~~~~~
drivers/media/platform/imx-pxp.c: In function 'pxp_irq_handler':
drivers/media/platform/imx-pxp.c:1012:9: error: 'IRQ_HANDLED' undeclared (first use in this function); did you mean 'IRQ_MODE'?
  return IRQ_HANDLED;
         ^~~~~~~~~~~
         IRQ_MODE
drivers/media/platform/imx-pxp.c:1012:9: note: each undeclared identifier is reported only once for each function it appears in
drivers/media/platform/imx-pxp.c: In function 'pxp_probe':

  ret = devm_request_threaded_irq(&pdev->dev, irq, NULL, pxp_irq_handler,
        ^~~~~~~~~~~~~~~~~~~~~~~~~
