ARM: tegra: colibri_t20: add missing pinmux

Explicitly add pinmux' for all T20 SoC ball groups now:
- Colibri Address/Data Bus (GMI) further pins used as GPIOs
- Colibri BL_ON
- Colibri EXT_IO*
- Colibri L_BIAS, LCD_M1 is muxed with LCD_DE today's display need DE,
  disable LCD_M1
- more Colibri LCD pins (L_* resp. LDD<*>)
- Colibri LCD (Optional 24 BPP Support)
- Colibri MMCCD
- uart_a_dsr and uart_a_dcd as GPIOs
- Colibri USB_CDET
- I2C3 (Optional)
- JTAG_RTCK
- LAN_RESET, LAN_EXT_WAKEUP and LAN_PME (All On-module)
- more NAND pins
- RESET_OUT
- THERMD_ALERT# (On-module), unlatched I2C address pin of LM95245
  temperature sensor therefore requires disabling for now
