Subject: [PATCH] Fix include guards for older kernel/u-boot sources
Linux kernels before 4.17 and U-Boot versions before 2018.07 use libfdt
include guards with leading underscores.
Those have been removed in dtc-1.4.7.
This patch handles both include guard types and allows the compilation
of older Linux kernel and u-boot sources.

[ThomasDS: also update fdt.h which has the same issue, seen on U-Boot
2011.03]
