Vybrid product family consists of several rather similar SoC which can be determined by softare during boot time. This allows use of variable ${soc} for Linux device tree files. Detect VF5xx CPU's by reading the CPU count register. We can determine the second number of the CPU type (VF6x0) which indicates the presence of a L2 cache.

This adds initial support for Colibri VF50/VF61 based on Freescale Vybrid SoC.

- CPU clocked at 396/500 MHz - DDR3 at 396MHz - for VF50, use PLL2 as memory clock (synchronous mode) - for VF61, use PLL1 as memory clock (asynchronous mode) - Console on UART0 (Colibri UART_A) - Ethernet on FEC1 - PLL5 based RMII clocking (E.g. No external crystal) - UART_A and UART_C I/O muxing - Boot from NAND by default - USB host and client support

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