Add lcd and backlight device definition. The pwm backlight stuff does
not allow to really set maximum pwm as with my custom driver but it's
better to use standard driver instead of out of tree driver.

Fix mach-n30.c to use the s3c_i2c0_set_platdata() call to register the
platform data with the system to get rid of any reliance on having a real
device structure available in memory.
Since s3c_i2c0_set_platdata() copies the data, mark the original as
__initdata so it is thrown away.

The AT2440EVB should not be changing the s3c_device_sdi.name as this is
part of the initialisation process done by the CPU detection process
and actually present in arch/arm/plat-s3c24xx/s3c24xx.c.

The mach-h1940.c file was using s3c_device_ where it really should be
calling these local definitions h1940_device to ensure they are not
mistaken for real s3c_devices when the device change is done.

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.

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.

The original TWL4030 keypad driver from linux-omap used KEY()
macro defined as (col, row), but while it was merged upstream
it was changed to use matrix keypad infrastructure, which uses
(row, col) format. Update the keymap in board file to match
layout of mainline driver.

The patch provides the following fixes:
- keep kernel small enough to boot with standard tools,
- ensure compatibility with both new and legacy distros,
- turn on support for recently added or fixed hardware features.

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.

Instead of allocating PCI devices I/O port bus addresses from the
000xxxxx I/O port range as intended, due to a bus versus physical
address mixup, the Kirkwood PCIe handling code inadvertently
allocated I/O port bus addresses from the f20xxxxx address range
(which is the physical address range of the PCIe I/O mapping window),
but then direct all I/O port accesses to bus addresses 000xxxxx,
which would then not be decoded at all.
Fix this by setting the base address of the PCIe I/O space struct
resource to KIRKWOOD_PCIE_IO_BUS_BASE instead of the incorrect
KIRKWOOD_PCIE_IO_PHYS_BASE, and fix up __io() to expect addresses
offsetted by the former instead of the latter.
(The suggested fix of directing I/O port accesses from the host to
bus addresses f20xxxxx instead has the problem that assigning full
32bit I/O port bus addresses (f20xxxxx) doesn't work on all PCI
devices, as not all PCI devices implement full 32 bit BAR registers
for I/O ports. We should really try to allocate I/O port bus
addresses that fit in 16 bits.)

The RealView PBX board has two 512MB blocks of memory - one at
0x70000000 (with 256MB mirror at 0) and another at 0x20000000. Only the
block at 0x70000000 (or the mirror at 0) may be used for DMA (e.g.
framebuffer). This patch adds the sparsemem definitions to allow the use
of all the memory split as follows:
256MB @ 0x00000000 (ZONE_DMA)
512MB @ 0x20000000 (ZONE_NORMAL)
256MB @ 0x80000000 (ZONE_NORMAL)
