This patch removes remaining inclusions of plat/regs-timer.h as
a preparation to remove the header.

As a part of this, things like save and restore of PWM registers are
removed from SoC-specific code, because it is handled in appropriate
drivers now.

Replace sysdev classes and struct sys_device objects used for "core"
power management by Samsung platforms with struct syscore_ops objects
that are simpler.

This generally reduces the code size and the kernel memory footprint.
It also is necessary for removing sysdevs entirely from the kernel in
the future.

Move IRQ support to mach-s3c64xx as it is unlikely to be re-used outside
this machine.

Move the register and GPIO definition files from plat-s3c64xx into the
machine include direcotry as they are unlikely to be reused outside
mach-s3c64xx.

This move includes removing the empty <mach/regs-clock.h> and replacing
it with the <plat/regs-clock.h> implementation.

Add support for saving the state of the IRQ registers over suspend.

This requires moving the S3C64XX UART registers into <plat/regs-serial.h>
and adding irq-pm.c which saves the state of all the IRQ registers.

The irq-pm.c saves all the IRQ registers, including the IRQ_EINT and
IRQ_EINT_GROUP registers as it was easier than adding three different
files. Also ensuring that all the registers are restored to the same
state as before suspend is considered to be the best thing to do.

Note, we do not suspend the VIC here, this is done by the VIC driver
itself.
