Update igep00x0 code with the following features:
- Add board and revision detection for the boards:
- IGEP0020-RF
- IGEP0020-RC
- IGEP0030-RG
- IGEP0030-RE
- Merge IGEP0020 and IGEP0030 mux tables
- Add suport to use GPIO_126, GPIO_127 and GPIO_129
- board_name environment variable displays board and revision information

This patch allows to use a single configuration (igep00x0_defconfig)
in order to boot multiple IGEP OMAP3 boards with the same binaries.
Boards tested are: igep0020-rc, igep0020-rf, igep0030-re and igep0030-rg.
This is done using some GPIOs that differs signal level between boards
and versions.
GPIO_129, used to detect versions, needs a proper power domain configuration
through TPS65950 VSIM regulator as omap3 pandora board implements into the
patch 7cad446b887b6764afe8a6706508236bbd4998d8.
Finally, MUX_IGEP0020 and MUX_IGEP0030 can be merged to MUX_DEFAULT,
because they share the same functionality.
