pru*-fw: Add AM64x pru firmwares

Add support for packaging AM64x PRU firmwares separately

Previously, AM64x platforms used the same PRU firmware binaries as
AM65x (the "am65x-sr2-*" files). This patch updates the recipes to
package dedicated AM64x PRU firmware binaries, ensuring that AM64x
devices use the correct firmware files.

The following changes are made:
- Add AM64x-specific firmware binaries to the TARGET lists in the
  prueth-fw, pruhsr-fw, pruprp-fw, and prusw-fw recipes.
- Update COMPATIBLE_MACHINE in pruprp-fw to include "am64xx".
- Add new PRU PRP firmware binaries for AM64x, as AM64x now supports
  PRP mode.
