ARM: mach-shmobile: sh73a0: Minimal setup using DT
Allow a minimal setup of the sh73a0 SoC using a flattened device tree.
In particular, Configure the i2c controllers using a flattened device tree.
SCI serial controller and CMT clock source, whose drivers do not yet
support configuration using a flattened device tree, are still configured
using C code in order to allow booting of a board with this SoC.
*** Please note that the clock initialisation scheme used in
this patch does not currently work with SMP as there
is a yet to be resolved lock-up in workqueue initialisation.
CONFIG_SMP must be disabled when using this code. ***
Includes update from Thierry Reding to no longer use gic_handle_irq()
