Recently the regs-syscon-power.h header was moved from
mach-s3c64xx/include/mach to mach-s3c64xx/, but cpuidle.c was not
updated to include the header from its new location, which caused
build error with CONFIG_CPU_IDLE enabled.
This patch fixed the problem by updating the include line with
proper header location.

The timekeeping is computed from the cpuidle core if we set
the .en_core_tk_irqen flag. Let's use it and remove the duplicated
code.

The states are now part of the cpuidle_driver structure, so we can
declare the states in this structure directly. That saves us an extra
variable declaration and a memcpy.

Entering and leaving WFI is really cheap so there's no reason to have much
of a residency requirement for the state. Lower it to 1ms.

Add a very basic cpuidle driver for S3C64xx which merely drives the CPU
into IDLE mode. We could do this with pm_idle but the more modern idiom
is to use cpuidle and the intention is to go further and support STOP
and DEEP-STOP states in conjunction with the pm_domain framework.
The actual state entry code was lifted from Tomasz Figa's work on spica.
