Mark the big-endian version as deprecated. When the xlnx-zynqmp-pmu machine's CPU was added in commit 133d23b3ad1 ("xlnx-zynqmp-pmu: Add the CPU and memory"), its 'endianness' property was set to %true, thus wired in little endianness. Both machine are included in the big-endian system binary, while their CPU is working in little-endian. Unlikely to work as it. Deprecate now as broken config so we can remove soon.
