Subject: [PATCH 06/08] mach-shmobile: KZM9D board Ethernet support V3

From: Magnus Damm <damm@...nsource.se>

Tie in the on-board Ethernet controller on KZM9D
and make use of the GPIO controller for external
IRQ pin support.

Signed-off-by: Magnus Damm <damm@...nsource.se>

 Changes since V2:
 - none, just bumped up version to match the V3 series

 Changes from V1:
 - none - this is the first public release
