Usage of DTS macros instead of hard-coded numbers makes code easier to
read. One does not have to remember which value means pull-up/down or
specific driver strength.

Replace duplicated macros in each DTSI file with a common macro coming
from header. Include the header in each pinctrl DTSI so further changes
could use it.
Although PIN_FUNC_SPC_2 does not bring much information about the
function itself, it still is more descriptive then hard-coded
number <2>.

This patch adds a convenient macro which constructs an Exynos pinctrl
pinconf node containing properties needed to configure sleep state of
given pin with given parameters. It will be used by further patch which
adds a large number of sleep states for pins that need such
configuration on certain boards.

The group has the samsung,pin-pud property set to 4, which is not a
correct value. This patch fixes this by replacing it with 3, which is
the correct value for pull-up.

Add separate nodes for the CAMCLK pin and turn off pull-up on camera
ports A, B. The video bus pins and the clock output (CAMCLK) pin need
separate nodes since full camera port is not used in some configurations,
e.g. for MIPI CSI-2 bus only CAMCLK is required and data/clock signal
use separate dedicated pins.

This patch modifies pin control groups of SD pins on EXYNOS4210
and EXYNOS4X12 to use drive strength 3 as a default value which
corresponds to S5P_GPIO_DRVSTR_LV4 in legacy non-DT code.
This is needed at least on Origen board for sdhci2 to work and
if any other drive strength is required on each board, we can
overide it.
