ARM: s5pv210: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

ARM: s5pv210: use private pm save/restore

The pm save/restore code is fairly small, so in order to
separate the s3c and s5p platforms, adding an s5p specific
copy instead of sharing it is actually easier.

ARM: make arrays containing machine compatible strings const

The definition

static const char *axxia_dt_match[] __initconst = {
...

defines a changable array of constant strings. That is you must not do:

*axxia_dt_match[0] = 'k';

but

axxia_dt_match[0] = "different string";

is fine. So the annotation __initconst is wrong and yields a compiler
error when other really const variables are added with __initconst.

As the struct machine_desc member dt_compat is declared as

const char *const *dt_compat;

making the arrays const is the better alternative over changing all
annotations to __initdata.

ARM: S5PV210: move <mach/regs-clock.h> into mach-s5pv210/

This moves <mach/regs-clock.h> into mach-s5pv210 so no more
include/mach/ under mach-s5pv210.
