We hint the 'has_rpu' property is no longer required since commit
6908ec448b4 ("xlnx-zynqmp: Properly support the smp command line
option") which was released in QEMU v2.11.0.

3 years later we feel safe enough to remove it without using the
usual deprecation policy.

This device is marked user_creatable = false, so the only thing
that could be setting the property is the board code that creates
the device. So the property is not user-facing and we can remove it
without going through the deprecation process.

(maybe noting the above in the commit message).
