ARM: dts: omap3-igep: Fix bus-width for mmc1.

Both, IGEPv2 and IGEP COM MODULE have a bus-width of 4 not 8, so fix this and
do not mux data pins from mmc1_data5 to mmc1_data7.

ARM: dts: omap3-igep: Add support for LBEE1USJYC WiFi connected to SDIO.

The LBEE1USJYC is a WiFi/BT combo module used on OMAP3-based IGEP boards. In
both cases, IGEPv2 Rev. C and IGEP COM MODULE, the module is connected using
the same MMC interface and uses the same GPIOs.

ARM: dts: omap3-igep*: Update to use the TI AM/DM37x processor.

Most of the boards are using the TI AM/DM37x processor, there is only a small
quantity of IGEP Processor Boards based on TI OMAP3530. So it's better use the
omap36xx.dtsi include instead of omap34xx.dtsi include.

To avoid confusion we have added to the model the (TI AM/DM37x) comment.

ARM: dts: omap3-igep0020: Add pinmux configuration for i2c.3

The IGEPv2 EDID interface is an I2C slave on bus number 3.
So the OMAP3 mux pins for the clock and data lines have to
be setup on the correct mode.

ARM: dts: omap3-igep0020: Add pinmux configuration for video

The IGEPv2 has a TFP410 DPI-to-DVI encoder attached to OMAP's
Display SubSystem (DSS).

Add mux setup for DSS pins and also for the GPIO 170 pin that
is used to ensure that the DVI-D is powered down on power up.
