colibri_vf61: initial integration

Add initial Colibri VF61 support based off Timesys' implementation for
Freescale's Vybrid Tower System TWR-VF65GS10:
- New machine ID.
- Default UART_A on SCI0.
- ESDHC2 only.
- 8-bit NAND.
- No quad SPI.
- FEC1 only.
- Enabled command line editing.
- PLL5 based RMII clocking (e.g. no external crystal).
- UART_A, UART_B and UART_C I/O muxing.
- Increase the available space for the U-Boot binary to half a megabyte
  by booting from gfxRAM rather than sysRAM0.
- Integrate factory configuration block handling for hardware version,
  MAC address and serial number to be passed to Linux.
- The U-Boot environment is stored in NAND flash.
- Fix long standing boot hang issue introduced by Freescale's Vybrid
  1.1 silicon.
- Proper 256 MB Nanya DDR3 RAM timings.

Tested on early Colibri VF61 prototypes V1.0b and V1.0c using SD card
(mandatory for initial loading) as well as NAND boot.
