Quite a bit of code gets removed, and some stuff moved around, mostly
the old samsung s3c24xx stuff. There should be no functional changes
in this series otherwise. Some cleanups have dependencies on other
arm-soc branches and will be sent in the second round.

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite. Remove arm_machine_restart() as this function
no longer does anything useful.
For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions. As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.

The timer irqs statically mapped from linux irq numbers 11 to 15 are
moved to the end of the statically mapped linux irq space. The GIC PPI
and SPI interrupts are relocated to start from 16 and 32 of the linux
irq space. This is a required to add device tree support for GIC and
Interrupt combiner for EXYNOS4.
A new macro 'IRQ_TIMER_BASE' specifies a platform specific base of the
linux virq number for the timer interrupts. For exynos4, this base is
set to end of the linux virq space. For the other S5P platforms, the
existing base '11' is retained.

The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.
This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.
