For most boards which define CONFIG_SPL_PAD_TO,
it is defined in config header files.
Currently, there exists only one exception, cam_enc_4xx board.
This patch moves CONFIG_SPL_PAD_TO definition
from board/ait/cam_enc_4xx/config.mk
to include/configs/cam_enc_4xx.h.
With this modification, we can delete a glue code
in the top level config.mk:
ifneq ($(CONFIG_SPL_PAD_TO),)
CPPFLAGS += -DCONFIG_SPL_PAD_TO=$(CONFIG_SPL_PAD_TO)
endif

New I2C framework, introduced after v2013.07 final release, imposed I2C
code adjustment for some Samsung boards - namely Trats, GONI and Universal_c210.
Those boards were using schematic based I2C enumeration (I2C_5, I2C_9).
However, new I2C framework imposes usage of logical I2C adapters numbering
(e.g. I2C_0, I2C_1, etc).
Additionally, I2C_GET_* macros were replaced with i2c_*_bus_num() functions.
Trats board gained definition of second soft I2C adapter.

IGEP boards now have Device Tree support in the mainline
kernel. To boot an IGEP board using a DT, a uEnv.txt plain
text file could be used to define a custom uenvcmd that will
be run by the default boot command.
It is more convenient to change the default boot command to
allow loading a FDT if it is stored in the boot dir of the
rootfs uSD/MMC partition.
If no FDT is found then the defaul command tries to boot a
zImage without a DT using legacy boot.

Creating a new the bit-mask to include all five bits and
modifying the 'hdmidet' command and internal detection
