As all PCS are using the neg_mode parameter rather than the legacy
an_mode, remove the ability to use the legacy an_mode. We remove the
tests in the phylink code, unconditionally passing the PCS neg_mode
parameter to PCS methods, and remove setting the flag from drivers.

Switch the Broadcom b53 driver to using the phylink_generic_validate()
implementation by removing its own .phylink_validate method and
associated code.

Populate the supported interfaces and MAC capabilities for the Broadcom
B53 DSA switches in preparation to using these for the generic
validation functionality.
The interface modes are derived from:
- b53_serdes_phylink_validate()
- SRAB mux configuration

PHYLINK takes care of filing the right information into
state->an_enabled, get rid of the read from the SerDes's BMCR register.

Add support for the Northstar Plus SerDes which is accessed through a
special page of the switch. Since this is something that most people
probably will not want to use, make it a configurable option with a
default on ARCH_BCM_NSP where it is the most useful currently.
The SerDes supports both SGMII and 1000baseX modes for both lanes, and
2500baseX for one of the lanes, and is internally looking like a
seemingly standard MII PHY, except for the few bits that got repurposed.
