This patch removes System MMU device driver from arm/plat-s5p tree
for transition to implement IOMMU driver.
Although controlling System MMU in this removing driver
is similar to the new IOMMU driver in the following patch,
the new one is almost rewrite of this driver and there is no
benefit to moving the driver file from arch/arm/ to drivers/iommu.

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.

This patch adds s3c_fb_driverdata s3c_fb_data_exynos5 for EXYNOS5
and adds extended timing control setting.

EXYNOS5 FIMD needs extended setting for video timing control.
Additional bits are added to VIDTCON2, VIDWxxADD2, VIDOSDxA and
VIDOSDxB registers in order to set timing value for lager resolution.

Also, address offset of VIDTCONx registers is changed from 0x0
to 0x20000, thus variable type should be changed to int type
to handle the address offset of VIDTCONx registers for EXYNOS5 FIMD.

and plat-s3c24xx dir. to just one mach-s3c24xx for them.

I think this should be sent to upstream via samsung tree because
this touches many samsung stuff.
