ARM: remove zte zx platform 



The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with
Baoyou Xie and Shawn Guo subsequently becoming maintainers after the
addition of the 64-bit variant.

However, the only machines that were ever supported upstream are the
reference designs, not actual set-top-box devices that would benefit
from this support. All ZTE set-top-boxes from the past few years seem
to be based on third-party SoCs. While there is very little information
about zx296702 and zx296718 on the web, I found some references to other
chips from the same family, such as zx296716 and zx296719, which were
never submitted for upstream support. Finally, there is no support for
the GPU on either of them, with the lima and panfrost device drivers
having been added after work on the zx platform had stopped.

Shawn confirmed that he has not seen any interest in this platform for
the past four years, and that it can be removed.

Thanks to Jun and Shawn for maintaining this platform over the past
five years.

* ZTE zx2967 family Power Domains



zx2967 family includes support for multiple power domains which are used

to gate power to one or more peripherals on the processor.



Required Properties:

  - compatible: should be one of the following.

      * zte,zx296718-pcu - for zx296718 power domain.

  - reg: physical base address of the controller and length of memory mapped

      region.

  - #power-domain-cells: Must be 1.



Example:



	pcu_domain: pcu@117000 {

		compatible = "zte,zx296718-pcu";

		reg = <0x00117000 0x1000>;

		#power-domain-cells = <1>;
