[PATCH u-boot-v2016.07] libfdt: Make it compatible with newer dtc

[Patrick Williams]

From: Alejandro Enedino Hernandez Samaniego <aehs29 at gmail.com>

DTC does not use an underscore for the LIBFDT_H and
LIBFDT_ENV_H variables, this causes an error since
u-boot does.

Remove the underscore from these variables to allow u-boot
to compile along with dtc.
