S5PC1xx Samsung SOC series has very similar frame buffer hardware, so a lot
of the code can be shared. Moved s3c64xx-specific s3c-fb register
definitions from mach-s3c6400 to common platform directory as regs-fb-v4.h.
The new v4 file will be common for S3C6400, S3C6410, S5PC100 and possibly
others. Some s3c64xx series specific defines (palette handling) were left
in s3c-6400/mach/regs-fb.h, because it is handled differently in S5PC1xx
series.

We inted to re-organise the plat-s3c/plat-s3c24xx/plat-s3c64xx into a
more generic plat-samsung with less code in the other plat- directories
to make it easier to port new devices and try and clear up some of the
naming issues with newer devices.

Start by creating a small arch/arm/plat-samsung with no actuall code in
so we can move items in as we process them.

Add this to arch/arm to allow it to build things once support is added.

    alpha: Clean up linker script using new linker script macros.

    Note that .data.page_aligned and .data.cacheline_aligned are now after
    _data; it was probably a bug that they were before it.

    Also, some explicit ALIGN(8)'s between various initcall sections were
    removed; this should be harmless as the implicit alignment of
    initcall_t was already 8.

Adjust OMAP3 frequency transition latency from 10,000,000uS to a more
reasonable 300,000uS.  This causes ondemand and conservative governors to
sample CPU load more often resulting in more responsive behavior.

Tested on Android 2.6.29; using this value and conservative governor, CORE
power consumption on Zoom2 was comparable to the old and unresponsive
10,000,000uS value while UI responsiveness was greatly improved.

With CONFIG_PM=y, the omapfb/lcdc device on Amstrad Delta, after initially
starting correctly, breaks with the following error messages:

omapfb omapfb: resetting (status 0xffffff96,reset count 1)
...
omapfb omapfb: resetting (status 0xffffff96,reset count 100)
omapfb omapfb: too many reset attempts, giving up.

Looking closer at this I have found that it had been broken almost 2 years ago
with commit 2418996e3b100114edb2ae110d5d4acb928909d2, PM fixes for OMAP1.

The definite reason for broken omapfb/lcdc behavoiur in PM mode
appeared to be ARM_IDLECT1:IDLIF_ARM (bit 6) put into idle regardless of LCD
DMA possibly running. The bit were set based on return value of the
omap_dma_running() function that did not check for dedicated LCD DMA
channel status. The patch below fixes this.

Note that the hardcoded register value will be fixed during the next merge
cycle to use OMAP_LCDC_ defines. Currently the OMAP_LCDC_ defines are local
to drivers/video/omap/lcdc.c, so let's not start moving those right now.
