Remove the duplicated code and use the cpuidle common code for initialization.

The en_core_tk_irqen flag is set in all the cpuidle driver which
means it is not necessary to specify this flag.
Remove the flag and the code related to it.

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 header file can be local in mach-s3c64xx/.

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.
