There is no reason to keep on using the __raw_{read,write}l() I/O
accessors in Renesas ARM driver code. Switch to using the plain
{read,write}l() I/O accessors, to have a chance that this works on
big-endian.

This code needs to call iounmap() on one error path.

Currently the R-Mobile "always-on" PM Domain is implemented by returning
-EBUSY from the generic_pm_domain.power_off() callback, and doing
nothing in the generic_pm_domain.power_on() callback. However, this
means the PM Domain core code is not aware of the semantics of this
special domain, leading to boot warnings like the following on
SH/R-Mobile SoCs:
sh_cmt e6130000.timer: PM domain c5 will not be powered off
Fix this by making the always-on nature of the domain explicit instead,
by setting the GENPD_FLAG_ALWAYS_ON flag. This removes the need for the
domain to provide power control callbacks.

The pm-rmobile driver is really a driver for the System Controller
(SYSC) found in R-Mobile SoCs. An equivalent driver for R-Car SoCs is
already located under drivers/soc/renesas/.
Hence move the pm-rmobile driver from arch/arm/mach-shmobile/ to
drivers/soc/renesas/, and rename it to rmobile-sysc.
Enable compile-testing on non-ARM and non-R-Mobile SoCs.
