colibri_vf50: initial integration

Add initial Colibri VF50 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.

Tested on early Colibri VF50 prototypes V1.0a using SD card (mandatory
for initial loading) as well as NAND boot.
