Commit b27b0727 (ARM: 7265/1: restart: S3C24XX: use new restart hook)
introduced the new restart hook also for the S3C244x cpus, but it
was only defined in the S3C2440 scope, i.e. when CPU_S3C2440 was
selected. Devices using the S3C2442 like the GTA02 normally don't select
this CPU which leads to compilation errors like:
    LD      .tmp_vmlinux1
  arch/arm/mach-s3c2440/built-in.o:(.arch.info.init+0x3c): undefined reference
to `s3c2440_restart'
  make: *** [.tmp_vmlinux1] Error 1

Therefore move the s3c2440_restart function to s3c244x.c which is
common to both cpus and also fix the naming to reflect this.

Commit 4a858cfc (arm: convert sysdev_class to a regular subsystem)
converted the samsung sysdevs into subsys_interface instances.

While the original add-function only had a (struct sys_device *)
parameter, the dev_add from subsys_interface needs
	(struct device *, struct subsys_interface *)
leading to "initialized from incompatible pointer type" warnings.

s3c2440 uses fclk/n (fclk divided by n) clock as one of the possible clocks used
to generate the baud rate clock. The divider 'n' in this case can be logically
represented outside of the uart controller.

This patch creates a new clock by name "fclk_n" for s3c2440 based platforms to
represent the fclk/n clock in the platform code. This clock provides a get_rate
callback that checks the UCON0/1/2 registers to determine the clock rate. The
samsung uart driver would receive the "fclk_n" clock name as one of the possible
baud rate clock options and the driver need not determine clock rate of fclk/n.

The sysdev.h file should not be needed by any in-kernel code, so remove
the .h file from these random files that seem to still want to include
it.

The sysdev code will be going away soon, so this include needs to be
removed no matter what.

ASoC audio for mini2440 platform in current kenrel doesn't work.
First problem is samsung_asoc_dma device is missing in initialization.
Next problem is with codec. Codec is initialized but never probed
because no platform_device exist for codec driver. It leads to errors
during codec binding to asoc dai. Next problem was platform data which
was passed from board to asoc main driver but not passed to codec when
called codec_soc_probe().
