The Ethernet switch embedded within the NXP LS1028A has 2 Ethernet ports
towards the host, for local packet termination. In current device trees,
only the first port is enabled. Enabling the second port allows having a
higher termination throughput.
Care has been taken that this change does not produce regressions when
using updated device trees with old kernels that do not support multiple
DSA CPU ports. The only difference for old kernels will be the
appearance of a new net device (for &enetc_port3) which will not be very
useful for much of anything.

Since the CPU port 4 of the switch is hardwired inside the SoC to go to
the enetc port 2, this shouldn't be something that the board files need
to set (but whether that CPU port is used or not is another discussion).
So move the DSA "ethernet" property to the common dtsi.

The LS1028A switch has 2 internal links to the ENETC controller.
With DSA's ability to support multiple CPU ports, we should mark both
ENETC ports as DSA masters.
