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.

Hook these platforms restart code into the new restart hook rather
than using arch_reset().

IRQs are already disabled by the time arch_reset() is called, so these
calls to local_irq_disable() instead arch_reset() are redundant.  Remove
them.

This adds core support for the ST-Ericsson U300 series
platforms: U300, U330, U335 and U365. Supports memory
mappings, interrupt controller, system timer (clocksource
and clockevents), and binds to the existing drivers for
the PrimeCells used in this design: PL190 (VIC), PL180
(MMC/SD host) and PL011 (UART). This is intented to serve
as starting point for our mainling work, more patches to
follow.
