Add a generic .dtsi device tree source file for the
common characteristics across IGEP Technology devices.

Changes since v3:
    - Remove VSIM regulator definition since now exists on twl4030.dtsi.
    - Add mux pins configuration for MMC device node.

Changes since v2:
    - Associate uart3_pins in uart3 device node.
    - Remove mcbsp2_ins for now until SMSC9221 Ethernet support is added.
