(ARM: __io abuse cleanup) cleanuped __io() -> IOMEM(),
but armadillo800eva was a outside of a target,
since "merge window" timing issue.
This patch cleanup it.

ARM is moving to stricter checks on readl/write functions,
so we need to use the correct types everywhere.

This patch is a bit ugly for shmobile, which is the only platform
that just uses integer literals all over the place, but I can't
see a better way to do this.

Move custom shmobile gpio code to a sh-gpio.h to remove the dependency
on mach/gpio.h. shmobile always uses gpiolib, so we can remove
__GPIOLIB_COMPLEX define from mach/gpio.h.

Make the power management code under arch/arm/mach-shmobile/ use
names of power domains instead of pointers to domain objects for
adding devices to the domains.  This will allow us to put the
domain objects into tables and register them all in one shot
going forward.

Since armadillo800eva has 2 sound cards,
and had reversed deferred probe order issue,
it was purposely registered in reverse order.

But it was solved by
1d29cfa5
(driver core: fixup reversed deferred probe order)

armadillo800eva board is expecting that
FSI-WM8978 is the 1st, and FSI-HDMI is the 2nd sound card.
This patch fixes it up

Because USB Func is controlled by external IRQ mode,
it is possible to control USB under A3SP domain to reduce power.
This patch enables it.

Armadillo800eva board switchs USB Host/Func by SW1.6,
So, the device to adds into domain is selected on this patch.

We can control renesas_usbhs driver as 2 way which are
autonomy mode and external IRQ trigger mode.

Autonomy mode is very easy settings for platform,
but it required USB power domain always ON,
since its connection/disconnection IRQ come from it.

If platform uses external IRQ trigger mode,
USB power domain can be OFF, since its
connection/disconnection IRQ come from external IRQ.

This patch enable external IRQ mode.
Now it is possible to add USB support on A4SP domain.

It solved CEU/VIO6C/2D-DMAC/VCP1/VPU5F/JPU/DISP memroy access error.

But MERAM driver can't control this issue,
since this work-around requires access to non-MERAM register address.
