ASoC: SOF: Intel: pci-mtl: Change the topology path to intel/sof-ipc4-tplg

The default topology path for IPC4 is intel/sof-ipc4-tplg with a symlink
to it as intel/sof-ace-tplg to support old kernels.
sof-bin has been released in this manner for almost two years now, it is
time to change the default path for MTL family.
