realtek: migrate PCS to fwnode_pcs provider/consumer API
PCS driver registers each SerDes as an fwnode_pcs provider in probe;
the resolver returns the cached or freshly-allocated rtpcs_link for
the requested (sds, link_idx) cell. DSA glue stops calling
rtpcs_create directly, drops .mac_select_pcs, and instead populates
phylink_config.num_available_pcs / fill_available_pcs from each
port's pcs-handle in phylink_get_caps. The rtl838x_port.pcs pointer
becomes a has_pcs bool populated at port probe via fwnode_property_
present, since nothing assigns the actual phylink_pcs anymore but the
"does this port use a PCS?" checks elsewhere still need a presence
flag.

Without .mac_select_pcs, phylink_major_config only searches the
pcs_list when state->interface is set in phylink_config.pcs_interfaces
(drivers/net/phy/phylink.c:1378). Populate it per port whenever the
port has a pcs-handle, listing the SerDes-routable interface modes for
each SoC variant -- without this, pcs_config / pcs_link_up are never
called and the SerDes is left unconfigured.

pcs_get_state still needs the MAC port number to index per-port link
status registers. Recover it at probe via rtpcs_map_links: walk the
sibling switch's ethernet-ports subtree (same backwards topology
lookup the sibling MDIO driver does for phy-handle), and for every
port whose pcs-handle resolves to one of our SerDes, store the port's
reg in sds->link_port[]. The resolver consults link_port[] when
allocating rtpcs_link and fails with -ENODEV if a consumer requested
a link the map step didn't record. Avoids a driver-side port_base
table that would have to encode per-SoC SerDes-to-port wiring (and
would silently break on non-contiguous variants); the DT is the
single source of truth.

Kconfig selects FWNODE_PCS.

79a6d2aab2 realtek: support configurable LED interface mode on RTL930x
Add support for changing the LED mode via the device tree.
Currently it always defaults to SERIAL mode. With this change,
one can also use the SINGLE_COLOR_SCAN and BI_COLOR_SCAN modes.

a30c6aa556 realtek: dsa: drop array from stp_get signature
Now that the stp_set() helpers have been refactored the stp_get()
helpers can be simplified. Drop the last array parameter. It is
no longer needed/evaluated by its callers.

4b8af19582 realtek: dsa: remove family_id check from xstp_state_set()
The rtldsa_port_xstp_state_set() function offers a generic interface
to its callers to set the bridge state of one port. While it calls
device specific helpers in the background it runs the data mapping
for each architecture with a family_id check on its own. So the
hardware abstraction is done in two places

- rtldsa_port_xstp_state_set() translates one half
- its helper translate the other half

Convert the signature of the device specific helpers so that this
function does not need to know any hardware details. Instead move
the table/offset/bit calculations into the helpers. This way the
code path uses a consistent hardware abstraction.

- rtldsa_port_xstp_state_set() calls the helpers
- helpers do the hardware translation

6ce041be4b realtek: dsa: drop legacy table commands
All consumers of legacy table commands have been refactored and
use the rtl_table helpers. Drop unused code.

rtl839x_exec_tbl2_cmd() cannot be dropped as it is still used
in the qos code. Keep it for now.

f7e76cc2e7 realtek: dsa: merge headers
There are currently two header files for the dsa driver. rtl83xx.h
and rtl838x.h. It is unclear for what reason they are separated.
Especially as one always includes the other. Merge those two files
into one.

8ea46952d6 realtek: dsa: common MSTI initialization
The dsa probing currently disable multiple spanning tree for RTL93xx
and keeps the bootloader setup for RTL83xx untouched. Additionally it
does this by checking for the family id. Refactor this to a common
"disable msti" setup.

To make it clear: From now on RTL83xx will also run in MSTI disabled
state. Tested on Linksys LGS310C.
