[PATCH] arm64: dts: create an include directory for DT bindings

[PATCH] arm64: dts: create an include directory for DT bindings

[Bintian Wang]

Some header files may be used by both DT files and kernel, and we
usually put them under <include/dt-bindings/>, and also include them
in DT files just like:
    #include <dt-bindings/xxx/xxx.h>
for exaple, some clock header files.

On arm64 platform, the compiler will report an error and terminate
when compiling DT files:
    dt-bindings/xxx/xxx.h: No such file or directory

In order to fix the compile error, create an include directory and symlink
dt-bindings from there to the actual location of include/dt-bindings/:

arch/arm64/boot/dts/include/dt-bindings -> ../../../../../include/dt-bindings

Such a patch was already on the list for the Juno board.
