[PATCH 2/3] mvebu: armada-8k: set fdtfile env from DEFAULT_FDT_FILE

[Josua Mayer <josua@solid-run.com>]

Developers find themselves with two options for defining the default
device-tree for a platform:

1. CONFIG_DEFAULT_DEVICE_TREE deciding which DT the u-boot build will
   use for itself.
2. CONFIG_DEFAULT_FDT_FILE deciding what should be the name of the
   actual device-tree file, when booting an OS.

Armada 8k config file used option 1 while adding a marvell/ directory
prefix. This causes issues when switching a board to CONFIG_OF_UPSTREAM
where the marvell/ prefix would be added twice.

Update the header file to set fdtfile variable instead from
CONFIG_DEFAULT_FDT_FILE. This allows clear separation between
device-tree for U-Boot and OS.
