The SPI controller platform devices should be compiled in
independent of the driver support, otherwise we might end
up with dev-spi built as kernel module.
Change this to make every machine select if it has some SPI
device and wants to build device definitions.

1. Moved common memory map definitions for S5P such as S5P_VA_XXX
into plat-s5p/include/mach/map-s5p.h from mach-s5p6440/include/mach.
2. Removed unnecessary definitions in the map.h and irq.c
3. Removed the unnecessary support for unaligned UART address
4. Renamed S5P_VA_VICx definitions as VA_VICx
5. Moved the definitons of VIC_BASE to plat-s5p/include/plat/irqs.h

The s5p6440-clock.c and s5p6440-init.c code in the plat-s5p is specific to
s5p6440 SoC based systems. So these files are being moved to the machine
directory of s5p6440. And these files are renamed in the machine directory.

Add an error print to s3c24xx_register_clocks to provide more useful
information when failing to register the clock.
I belive this was originally left out due to the possibility of a
problem with low-level debugging code. However, if the low-level
debug code is not functional by now there will be a whole other set of
problems being presented to the system.

The s3c64xx_spi_set_info() sets one of two platform data structures depending

We need a way to pass controller specific information to the SPI driver.
For that purpose new headers are made.
SPI Controller is assumed 'type-s3c64xx' and can be defined for newer SoCs.
Hence, that part is placed under plat-samsung to be shared across newer SoCs.
SoC specific part - spi source clocks, will be placed
under plat-<soc>/include/plat/

The WARN_ON() was only checking the first clock in the array, instead of
being executed for each clksrc clock being registered.
Since this is an array of clocks, WARN_ON() does not provide a lot of
useful information about the problem, so change to using printk(KERN_ERR)
to report the problem to the console.
As a note, we still try and register the clock even if these problems are
present just in case and to avoid changing the behaviour of the registration
process.

Since the mach-smdk6410.c file claims it can start up the
smsc9115 ethernet device on the board, it should take care
about configuring the necessary chip select nCS1 so it can
see the chip. The select defaults to 8-bit mode so without
config the Ethernet doesn't work.
This patch uses the new SROM definitions to set nCS1 to the
state found in the Samsung U-Boot port for 6410. It may be
more conservative that it needs to be since those settings
were marked as for CS8900A also using this chip select.
But this change is enough to get the ethernet working when
booted with Qi.
