NXP i.MX NETC is a TSN capable Ethernet IP. It may support
ENETC MACs, or/and multiple ports switch.
The ENETC MAC was handled by eth_nxp_imx_netc driver.
This DSA driver is to support NETC switch device.
Current driver supports DSA with limitation that only switch
function is available without management via DSA master port.
DSA master port support is TODO work.
Take i.MX RT1180 NETC hardware as an example.

DTS property attributes are (by default) not required.
Explicitly specifying `required: false` is redundant.
Perhaps a warning to that effect would be useful.

All in tree device drivers use some form of DEVICE_DT_GET
so we no longer need to require label properties.
