Since commit 21cc1b7ede ("ARM: shmobile:
use machine specific hook for late init") suspend and CPU idle are not
initialized automatically anymore. Set shmobile_init_late() as the
machine late init hook to initialize them.

Use DT_MACHINE_START() on the emev2 based KZM9D board.
Also include a tiny DTS file to describe the board and
update the Kconfig dependencies to select CONFIG_USE_OF.
Update the SMP glue code to use OF for matching.

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

This is V3 of Emma Mobile EV2 SMP support.
At this point only the most basic form of SMP operation
is supported. TWD and CPU Hotplug support is excluded.
Tied to both the Emma Mobile EV2 and the KZM9D board
due to the need to switch on board in platsmp.c and
the newly introduced need for static mappings.
The static mappings are needed to allow hardware
acces early during boot when SMP is initialized.
This early requirement forces us to also map in
the SMU registers.

V3 of basic KZM9D board support. At this point a quite
thin layer that makes use of the Emma Mobile EV2 SoC code.
