fdt: ARM: Add fdtcontroladdr to set device tree address in environment
This adds support for a new environment variable called 'fdtcontroladdr'. If
defined, the hex address is used as the address of the control fdt for U-Boot.
Note: I have not changed CONFIG_PRAM section as I already have an
outstanding patch on that.
