From: YannickV <Y.Vossen@beckhoff.com>

This commit introduces a new machine, derived from xilinx-zynq-a9,
as a starting point for the Beckhoff CX7200 integration. Functions
and structs are renamed to delimit the CX7200 board emulation from
the existing Zynq emulation.

At this stage, the new machine is a direct copy of hw/arm/xilinx_zynq.c.
Future commits will adapt it to match the CX7200 hardware requirements.
