arm: vf610: initial integration for Colibri VF50/VF61

This adds initial support for Colibri VF50/VF61 based on Freescale
Vybrid SoC. The board support package is based on Freescale Tower
board, with following differences:
- CPU clocked at 500MHz
- Use PLL2 as DDR3 clock (400MHz)
- New Machine ID
- Console on UART1 (Colibri UART_A)
- Ethernet on FEC1
- Enabled command line editing
- PLL5 based RMII clocking (e.g. no external crystal)
- UART_A and UART_C I/O muxing
- Boot from OCRAM gfxRAM
- Boot from NAND by default

Tested on Colibri VF50/VF61 booting using serial loader over UART.
