s3c24xx and s3c64xx have a lot in common, but are split across three
separate directories, which makes the interaction of the header files
more complicated than necessary.
Move all three directories into a new mach-s3c, with a minimal
set of changes to each file.

Rather than have the cpufreq drivers touch include the
common headers to get the constants, add a small indirection.
This is still not the proper way that would do this through
the common clk API, but it lets us kill off the header file
usage.

The cpufreq drivers are split between the machine directory
and the drivers/cpufreq directory. In order to share header
files after we convert s3c to multiplatform, those headers
have to live in a different global location.
Move them to linux/soc/samsung/ in lack of a better place.

Replace GPL license statements with SPDX license identifiers (GPL-2.0
and GPL-2.0+). The h1940-bluetooth.c was licensed under GPL-1.0. This
also adds GPL-2.0 to few files lacking license statement.

The s3c24xx cpufreq driver needs to change the mpll speed and was doing
this by writing raw values from a translation table into the MPLLCON
register.
Change this to use a regular clk_set_rate call when using the common
clock framework and only write the raw value in the samsung_clock case.
The s3c cpufreq driver does already aquire the mpll, so simply add a reference
to struct s3c_cpufreq_config to let set_fvco access it.
While struct clk is opaque the differenciation between samsung clock and
common clock is kept, as the samsung-clock mpll clk does not implement a
real set_rate.

The "index" field of struct cpufreq_frequency_table was never an
index and isn't used at all by the cpufreq core. It only is useful
for cpufreq drivers for their internal purposes.
Many people nowadays blindly set it in ascending order with the
assumption that the core will use it, which is a mistake.
Rename it to "driver_data" as that's what its purpose is. All of its
users are updated accordingly.

Since header mach/regs-mem.h is used only into mach-s3c24xx/,
this patch moves the header file in local.

This patch is for just moving plat-s3c24xx/*.c into mach-s3c24xx/, so
that we could remove plat-s3c24xx directory. But since the PLAT_S3C24XX
is used in drivers, the statement is not deleted and it will be sorted
out next time.
