This patch adds pinmux and i2c pinctrl DT node for IFC6410 board.
It also adds necessary DT support for i2c eeprom which is present on
IFC6410.

Tested on IFC6410 board.

Signed-off-by: Kiran Padwal <kiran.padwal@smartplayin.com>

Changes since v2:
 - Renamed pinmux i2c subnode "i2c1_pinmux" to "i2c1".
 - Removed labes of node.
 - Used canonical value as "okay" instead of "ok".
 - Used macros.

Changes since v1:
 - Renamed pinmux phandle "qcom_pinmux" to "tlmm_pinmux".
 - Updated pinmux interrupt.
