sh: intc: optimize intc IRQ lookup
This ensures that the sense/prio lists are sorted at registration time,
enabling us to use a simple binary search for an optimized lookup
(something that had been on the TODO for some time).

sh: intc: Make global intc controller counter static.
No need to expose this globally since it's only used for core accounting.

PM / shmobile: Don't include SH7372's INTCS in syscore suspend/resume
Since the SH7372's INTCS in included into syscore suspend/resume,
which causes the chip to be accessed when PM domains have been
turned off during system suspend, the A4R domain containing the
INTCS has to stay on during system sleep, which is suboptimal
from the power consumption point of view.
For this reason, add a new INTC flag, skip_syscore_suspend, to mark
the INTCS for intc_suspend() and intc_resume(), so that they don't
touch it. This allows the A4R domain to be turned off during
system suspend and the INTCS state is resrored during system
resume by the A4R's "power on" code.

sh: intc - convert sysdev_class to a regular subsystem
After all sysdev classes are ported to regular driver core entities, the
sysdev implementation will be entirely removed from the kernel.

sh: Use struct syscore_ops instead of sysdevs
Convert the SuperH clocks framework and shared interrupt handling
code to using struct syscore_ops instead of a sysdev classes and
sysdevs for power managment.
This reduces the code size significantly and simplifies it. The
optimizations causing things not to be restored after creating a
hibernation image are removed, but they might lead to undesirable
effects during resume from hibernation (e.g. the clocks would be left
as the boot kernel set them, which might be not the same way as the
hibernated kernel had seen them before the hibernation).
This also is necessary for removing sysdevs from the kernel entirely
in the future.

sh: intc: Split up the INTC code.
This splits up the sh intc core in to something more vaguely resembling
a subsystem. Most of the functionality was alread fairly well
compartmentalized, and there were only a handful of interdependencies
that needed to be resolved in the process.
This also serves as future-proofing for the genirq and sparseirq rework,
which will make some of the split out functionality wholly generic,
allowing things to be killed off in place with minimal migration pain.
