(ARM: __io abuse cleanup) cleanuped __io() -> IOMEM(),
but setup-r8a7779.c was out of target,
since it directly used (void __iomem __force *) instead of __io().
This patch cleanup it.

Instead of giving a name to every r8a7779's PM domain object, put
them all into a table and initialize them all together in a loop.

Fix SMP TWD boot regression on r8a7779 based platforms caused by:

4200b16d ARM: shmobile: convert to twd_local_timer_register() interface

After the merge of the above commit it has been impossible to boot
r8a7779 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The
kernel crashes at smp_init_cpus() timing which is before the console
has been initialized, so to the user this looks like a kernel lock up
without any particular error message.

This patch fixes the regression on r8a7779 by moving the TWD
registration code from smp_init_cpus() to sys_timer->init() time.

setup-r8a7779.c has grown a new user of the __io() macro. Rob Herring's
PIO cleanup series already gets rid of all other uses in shmobile, so
we should ensure that this one gets removed as well.

Move the SoC specific timer code from Marzen board code
to r8a7779 setup code. This makes is possible to share
the SoC specific timer code across boards and it also
removes the need for a board specific timer structure.

Update the r8a7779 SoC and the Marzen board to make use of

Remove NR_IRQS and explicitly include mach/irqs.h as needed. shmobile
properly allocates irq_descs for each irqchip, so setting .nr_irqs for
each machine is not needed.

Add power domain control support for the r8a7779 SoC V2.

This adds support for 4 power domains for I/O Devices
together with code that can be used for CPU cores as well.

The only out of the ordinary experience is the need for
ioremap() of SYSC registers. Because of that we need to
execute some init function before setting up the domains.

Initial support for the r8a7779 SoC and the Marzen board (V2).

Only SCIF ports and the TMU are supported at this point.

To keep things simple only entity-mapped virt-to-phys mappings
are supported. This forces drivers and other SoC glue code to
make use of ioremap(). We cannot support early serial console
due to virtual address space collisions with the ARM kernel.
