This patch modifies the S3C I2C driver to suppport EXYNOS5.
The cahnges made to driver are as follows:
- I2C base address is passed as a parameter to many
functions to avoid multiple #ifdef
- Channel initialisation is moved to a commom funation
as it is required by i2c_init.
- Hardcoding for I2CCON_ACKGEN removed.
- Replaced printf with debug.
- Checkpatch issues resolved.
- Pinmux setting will be done in board/samsung/smdk5250/smdk5250.c
to avoid repeated setting of gpio lines, as it have multi bus support.

Let's clear the sr register before waiting for
bit to be set, instead of clearing it after
hardware sets it. No real operational difference here,
but allows combining of i2c_imx_trx_complete and
i2c_imx_bus_busy in later patches.

This is an improved version of the driver patch original
submitted by Graeme Smecher <graeme.smecher@mail.mcgill.ca>
The changes are:
- remove hard coded Xilinx BSP defines (XPAR_SPI_*) and
use CONFIG_SYS_SPI_BASE from config.h instead
- add extensive register struct definitions
- remove offset calculation for register access and
use the new register struct instead
- move default SPI controller configuration from
spi_setup_slave() to spi_claim_bus()
- add spi_set_speed()
- insert SPI controller deactivation in spi_release_bus()
- protect while loops in spi_xfer() with counter / timeouts
- support SPI mode flags: LSB_FIRST, CPHA, CPOL, LOOP

Some architectures, for example Microblaze, doesn't need a
splitted device tree because every Microblaze hw design is
different. The individuell Microblaze device tree will be
auto generated by FPGA design tools and could be used directly
with dtc.
The auto generated dts for Microblaze can not processed by CPP.
Unfortunately that is the default procedure in U-Boot to merge
a splitted device tree (substitution of ARCH_CPU_DTS).
Microblaze will never use the ARCH_CPU_DTS substitution and we
introduce the new board specific substitution variable BOARD_DTS
that points into vendor/board/dts subdir with the file name
of CONFIG_DEFAULT_DEVICE_TREE. The common dts file in vendor/dts
subdir (defined by CONFIG_DEFAULT_DEVICE_TREE) contain a single
include line that can processed by CPP:
/include/ BOARD_DTS
