igep00x0: merge igep0020 and igep0030 defconfigs to igep00x0_defconfig
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 and board_rev environment variables display board and
revision informations
- Move dtb name selection from code to boot script
