qualcommbe: drop "port_" from PPE port clock and reset names

The lastest ethernet PPE driver, uses "mac", "rx", and "tx", without
the "port_" prefix for the port clocks and resets. The PPE ports are
declared by the device dts. In order to support v6.12 and v6.18
kernels simultaneously, update the kernel patches and kiwi-dvk
devicetree to use the newer naming scheme.
