[U-Boot] [PATCH] sunxi: allow CONFIG_DEFAULT_FDT_FILE override

[Martin Kelly <mkelly@xevo.com>]

Currently, sunxi-common.h ignores CONFIG_DEFAULT_FDT_FILE and assumes
the kernel fdtfile and the u-boot devicetree names are the same.
Although this is typically the case, sometimes you might want to
customize one of these differently, so it's useful to allow them to be
different.

Add logic in sunxi-common.h to respect CONFIG_DEFAULT_FDT_FILE, if set,
and default to the values it currently uses.
