Subject: [PATCH v3 5/5] uio: uio_pdrv_genirq: Add "marvell,88e2040" to dt compatible list

The marvell,88e2040 is a N-BaseT Ethernet PHY which requires a userspace
driver. uio_pdrv_genirq can be used to provide interrupts to such a
userspace driver.

Changes in v3:
- (replaces "uio: add default compatible string to uio_pdrv_genirq")
- As suggested by Rob, add specific dt bindings for the hardware I'm
  supporting. uio_pdrv_genirq is one potential implementor of a compatible
  driver.
