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.
