Add the required DMA masks to the hs-otg device definition to allow DMA
to work with it.

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.

The S3C2412 has a fractional baud rate register, this patch adds the
corresponding flag to the UART definition to allow generation of more
precise baud rates for the various clock combinations.

Add SERIAL_SAMSUNG_UARTS_4 to mop up the number of cases currently using
four Samsung compatible UARTS.

As part of the development process, it is hoped PLAT_S3C is either removed
from all of the PLAT_SAMSUNG derived platforms or removed entirely. It is
also better to use PLAT_SAMSUNG as this is the current base of all Samsung
devices.

Change the two places that use PLAT_S3C to use PLAT_SAMSUNG

Making the code depend on CONFIG_SND_S3C24XX_SOC means that if the ASoC
code is build modularily, the boards will fail to link due to the device
code also being built as a module.

As per Mark Brown's suggestions, just compile this always as it is expected
many machines will have audio.

Also move the obj-y line out of the device setup area into a new area just
for devices.

   Shouldn't this be DMA_BIT_MASK(32)?
