====================
Unique mv88e6xxx IRQ names

There are a few boards which have multiple mv88e6xxx switches. With
such boards, it can be hard to determine which interrupts belong to
which switches. Make the interrupt names unique by including the
device name in the interrupt name. For the SERDES interrupt, also
include the port number. As a result of these patches ZII devel C
looks like:

 50:          0  gpio-vf610  27 Level     mv88e6xxx-0.1:00
 54:          0  mv88e6xxx-g1   3 Edge      mv88e6xxx-0.1:00-g1-atu-prob

 90:          0  mv88e6xxx-g2   4 Edge      !mdio-mux!mdio@2!switch@0!mdio:04
 95:          3  mv88e6xxx-g2   9 Edge      mv88e6xxx-0.2:00-serdes-9
 96:          0  mv88e6xxx-g2  10 Edge      mv88e6xxx-0.2:00-serdes-10
101:          0  mv88e6xxx-g2  15 Edge      mv88e6xxx-0.2:00-watchdog

Interrupt names like !mdio-mux!mdio@2!switch@0!mdio:01 are created by
phylib for the integrated PHYs. The mv88e6xxx driver does not
determine these names.
