Add board_usb_phy_mode function for detecting whether a port is
being used as host or client using a GPIO. On Colibri Vybrid we
provide GPIO 102 for this very same purpose.

Commit 3f353cecc ("vf610: refactor DDRMC code") changed the original
bstlen field from 3 to 0.
Restore the original value for proper behaviour.
Based on the patch from Anthony Felice <tony.felice@timesys.com>
for the vf610twr board.

The VF610 DDRMC driver code contains settings which are
board-specific. Move these out to boards so that new boards
can define their own without having to modify the driver.

Add IOMUX for the pad used as USB pen. This needs to be driven low for
the Iris and Viola boards where it is pulled up high by default. This is
required for the USB host functionality to work on these boards. Use the
board specific weak initialisation function, to drive the pin low which
would be called on "usb start".

Most of the drivers available for Vybrid are not yet converted
to OF model to use device tree model, only few drivers
like SPI and GPIO drivers use device trees.
Add separate defconfig for who needs to use device tree model.
Later this can be integrated to single defconfig.

Inorder to use the pins as GPIO, apart from setting the alt-function,
pinmuxing need to be done, this patch adds pinmux entries of
few GPIOs.

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