As a final bit of preparation for converting to ARCH_MULTIPLATFORM,
change the interrupt handling for s3c24xx to use sparse IRQs.
Since the number of possible interrupts is already fixed and relatively
small per chip, just make it use all legacy interrupts preallocated
using the .nr_irqs field in the machine descriptor, rather than actually
allocating domains on the fly.

There is a return above the break. The break here is unnecessary.
Remove it.

pwm_request() is deprecated because (among others) it depends on a global
numbering of PWM devices. So register a pwm_lookup to pick the right PWM
device (identified by provider and its local id) and use pwm_get().
Before this patch the PWM #1 was used. This is provided by the
samsung-pwm device which is the only PWM provider on this machine. The
local offset is 1, see also commit c107fe904a10 ("ARM: S3C24XX: Use PWM
lookup table for mach-rx1950") with a similar conversion for PWM #0.
As a follow up specify the period only once and symmetrically use pwm_put()
instead of pwm_free() to drop the reference.

This converts the S3C ADC battery to use GPIO descriptors
instead of a global GPIO number for the charging completed
GPIO. Using the pattern from the GPIO charger we name this
GPIO line "charge-status" in the board file.

Pull ARM SoC platform updates from Olof Johansson:
"SoC changes, a substantial part of this is cleanup of some of the
older platforms that used to have a bunch of board files.
In particular:
- Remove non-DT i.MX platforms that haven't seen activity in years,
it's time to remove them.
- A bunch of cleanup and removal of platform data for TI/OMAP
platforms, moving over to genpd for power/reset control (yay!)
- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).
There are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones are:
- New SoC: Hisilicon SD5203, ARM926EJ-S platform.
- Cpufreq support for i.MX7ULP"

PWM timer initialization has two independent implementations - one for
S3C24xx and one for S3C64xx. The naming however was always the same
and before also the declaration was shared. This is confusing, error
prone and might cause issues when trying to build multiplatform kernel.

A lot of header files are only used internally now, so they can be moved
to mach-s3c, out of the visibility of drivers.

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.
