Changelog:

v6:
Removed extra boards, I'll add them when submitting their individual
DTS files. Rephrase the subject to add "zte" and remove the redundant
use of "binding".

Moved the devicetree bindings patch ahead of the implementation patches.

Moved the MAINTAINERS section from "ZX29" to "ARM/ZTE".
