This is the only part of plat-samsung that is really
shared between the s3c and s5p ports. Moving it to
drivers/soc/ lets us make them completely independent.

The pm-debug code is one of the few things shared between
s3c24xx/s3c64xx and the newer s5pv210. In order to make s5pv210
independent of plat-samsung, change the common bits of this code to no
longer reference the s3c specific bits.
In particular, all the CPU checks need to be moved out of the common
code into platform specific files.

On s3c24xx and s3c64xx, this is just a wrapper around
s3c_pm_debug_init_uart(), but this function does not exist on s5pv210,
which always uses an empty stub as CONFIG_SAMSUNG_ATAGS is normally
not set.
In a configuration that supports both s5pv210 and s3c64xx, we would
always call the s3c64xx function, which is probably incorrect when
running on s5pv210.
Remove the function call completely on s5pv210 and skip the wrapper on
s3c as a cleanup.
As a side-effect, the s3c64xx behavior is now always the same, regardless
of whether it is a DT-only configuration or both DT and ATAGS are
supported for booting.

The pm-core.h file does not include all the necessary headers,
and has a static declaration for a function that is not
defined in the same file, causing SAMSUNG_PM_DEBUG to
break on s3c24xx:
arch/arm/mach-s3c24xx/include/mach/pm-core.h:50:91: warning: 's3c_pm_show_resume_irqs' used but never defined
arch/arm/mach-s3c24xx/include/mach/pm-core.h: In function 's3c_pm_debug_init_uart':
arch/arm/mach-s3c24xx/include/mach/pm-core.h:16:34: error: 'S3C2410_CLKCON' undeclared (first use in this function)
unsigned long tmp = __raw_readl(S3C2410_CLKCON);
^
This moves the code around slightly to avoid the errors.

Due to recently merged patches and previous merge conflicts, the Samsung
PM Debug functionality no longer can be enabled. This patch fixes
incorrect dependency of SAMSUNG_PM_DEBUG on an integer symbol and adds
missing header inclusion.

Not all Samsung SoC platforms are going to use the legacy Samsung PM
code enabled by CONFIG_SAMSUNG_PM_DEBUG. To allow using Samsung PM debug
helpers on such platforms, related code is moved to separate file and
a plat/pm-common.h header is added to separate legacy and generic code.
