ac84eb47cc kbuild: remove unnecessary variable initializaions
Clearing obj-y, obj-m, obj-n, obj- in each Makefile is
a useless habit.

They are non-exported variables; therefore they are always empty
whenever descending into each subdirectory.
(Moreorver, obj-y and obj-m are also set to empty at the beginning
of scripts/Makefile.build)

defd9da51d ARM: S3C24XX: remove legacy clock code
With the move to the common clock framework completed for s3c2410, s3c2440
and s3c2442, the legacy clock code for these machines can go away too.

This also includes the legacy dclk code, as all legacy users are converted.

a28d618e2e ARM: S3C24XX: convert s3c2440 and s3c2442 to common clock framework
Convert all machines using these cpus to use the ccf clock driver
instead of the legacy Samsung clock implementation.

Some of the more esotheric machines will probably need a fixup, as they
do strange things to the clkout outputs, that I did not really understand
nor have the hardware to check.

Fix up trivial conflicts in drivers/gpio/gpio-samsung.c that look much
worse than they are: the exonys5 init code was refactored in commit
fd454997d6 ("gpio: samsung: refactor gpiolib init for exynos4/5"), and
then commit f10590c983 ("ARM: EXYNOS: add GPC4 bank instance") added a
new gpio chip define and did tiny updates to the init code.

So the conflict diff looks like hell, but it's actually a fairly simple
change.

ec2cc753f4 ARM: S3C24XX: Consolidate Simtec extensions
The Simtec extension didn't follow a specific naming scheme for files
and config options until now. This distributed the files throughout
the whole mach-s3c24xx directory.

This patch fixes the naming of files and option names and also creates
a simtec.h header instead of using many one-liners.

As the plat/audio-simtec.h only contains the platform-data struct now,
it can also move to include/sound in a later patch.
