If neither CONFIG_SUSPEND nor CONFIG_CPU_IDLE is set in the kernel
configuration file, build error occurs in
arch/arm/mach-shmobile/pm-sh7372.c.

Fix it by rearranging #ifdefs in that file to make the
definition of sh7372_suspend_init() depend only on
CONFIG_SUSPEND and the definition of sh7372_cpuidle_init()
depend only on CONFIG_CPU_IDLE.

The sh7372's cpuidle code uses cpu_suspend() and cpu_resume() in
its implementation of the .enter() callback for deeper C-states, so
make ARCH_SH7372 select ARM_CPU_SUSPEND if CPU_IDLE is set to satisfy
all of the build dependencies (it has to be selected for CONFIG_PM
as well for the system suspend handling).

Add generic DT board support for the sh7377 SoC.

SCIF serial ports and timers are kept as regular
platform devices. Other on-chip and on-board devices
should be configured via the device tree.

At this point there is no interrupt controller support
in place but such code will be added over time when
proper IRQ domain support has been added to INTC.

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.

On systems, using regulators to supply power to devices, if the REGULATOR
Kconfig option is disabled, regulator API stubs will be used, which often
suffices to bring a default configuration up. If REGULATOR is enabled but
respective regulator drivers are inactive, the real regulator API calls
will be used, which in the absence of drivers will fail to provide
services. This patch prevents such a problem on sh-mobile boards by
forcing REGULATOR_FIXED_VOLTAGE on if REGULATOR is selected.

Drivers for several devices on mackerel, including all SDHI instances, the
MMCIF controller and the SMSC9220 ethernet chip use regulators to control
power supply to their devices. MMC drivers need to be able to at least
retrieve voltage values from supplying regulators, whereas the smsc911x
driver only enables and disables chip power supplies without further looking
at them. This patch adds two fixed voltage regulators to describe 1.8V and
3.3V supplies on the board and a dummy regulator for SMSC9220.
