arm: xlnx-zynqmp: Preface CPU variables with "apu"

Browse Source 
The CPUs currently supported by zynqmp are the APU (application
processing unit) CPUs. There are other CPUs in Zynqmp so unqualified
"cpus" in ambiguous. Preface the variables with "APU" accordingly, to
prepare support adding the RPU (realtime processing unit) processors.
