dmaengine: ti: k3-psil: Use soc_device_match to get the psil map
Instead of separate of_machine_is_compatible() it is better to use soc_device_match() and soc_device_attribute struct to get the PSI-L map for the booted device. By using soc_device_match() it is easier to add support for new devices.
