Rework chip_info to tell SERDES ports from xMII ones, identify the port type
at runtime from the pad configuration, and add a phylink PCS driver for the
internal SerDes, so that the link of SERDES ports can be established through
in-band negotiation instead of a fixed configuration.

v4:
  - fix 1000basex
  - YT921X_SPEED_NUM -> YT921X_SPEED_INVALID
  - reword commit message
v3: https://lore.kernel.org/r/20260917185010.3189199-1-mmyangfl@gmail.com
  - fix build error
v2: https://lore.kernel.org/r/20260916164310.3168269-1-mmyangfl@gmail.com
  - Remove YT921X_PORT_MASK_* macros
  - code style nits
  - unconditionally write BMCR_ANRESTART
