[meta-xilinx] [PATCH 1/7] pmu-firmware: Make the recipe provide virtual/pmu-firmware

[Nathan Rossi]

Make the pmu-firmware recipe provide a non-prefixed
virtual/pmu-firmware. Due to the common use of a class extender the
PROVIDES variable will be remapped with the 'zynqmp-pmu-' prefix. In
order to ensure the provider is always without a prefix modify the
PROVIDES after the recipe has been parsed (and any class extender
mapping is already processed).

Additionally set the zcu102-zynqmp machine to use the
virtual/pmu-firmware target and set the zynqmp-pmu-pmu-firmware recipe
as the default provider.
