net: airoha: add phylink support

This commit adds phylink support for each GDM port, configuring internal
interface modes for GDM1 and necessary PCS settings for external PHYs or SFP
cages on GDM2/3/4. It also updates the ethtool get and set link ksettings
functions to use phylink.

[Severity: Low]
Since this patch fully supports phylink and implements set_link_ksettings,
should airoha_ethtool_ops in drivers/net/ethernet/airoha/airoha_eth.c also
include the .nway_reset callback?

Without this callback, userspace attempts to manually restart
autonegotiation via "ethtool -r <interface>" will receive -EOPNOTSUPP. It
is standard in phylink conversions to also provide an nway_reset wrapper
that calls phylink_ethtool_nway_reset(dev->phylink) to allow administrators
to trigger autonegotiation restarts.
