[net-next,v5,0/9,RFT] net: dpaa: Convert to phylink

This series converts the DPAA driver to phylink.

I have tried to maintain backwards compatibility with existing device
trees whereever possible. However, one area where I was unable to
achieve this was with QSGMII. Please refer to patch 2 for details.

All mac drivers have now been converted. I would greatly appreciate if
anyone has T-series or P-series boards they can test/debug this series
on. I only have an LS1046ARDB. Everything but QSGMII should work without
breakage; QSGMII needs patches 7 and 8. For this reason, the last 4
patches in this series should be applied together (and should not go
through separate trees).

This series depends on [1] and [2].

Changes in v5:
- Add Lynx PCS binding

Changes in v4:
- Use pcs-handle-names instead of pcs-names, as discussed
- Don't fail if phy support was not compiled in
- Split off rate adaptation series
- Split off DPAA "preparation" series
- Split off Lynx 10G support
- t208x: Mark MAC1 and MAC2 as 10G
- Add XFI PCS for t208x MAC1/MAC2

Changes in v3:
- Expand pcs-handle to an array
- Add vendor prefix 'fsl,' to rgmii and mii properties.
- Set maxItems for pcs-names
- Remove phy-* properties from example because dt-schema complains and I
  can't be bothered to figure out how to make it work.
- Add pcs-handle as a preferred version of pcsphy-handle
- Deprecate pcsphy-handle
- Remove mii/rmii properties
- Put the PCS mdiodev only after we are done with it (since the PCS
  does not perform a get itself).
- Remove _return label from memac_initialization in favor of returning
  directly
- Fix grabbing the default PCS not checking for -ENODATA from
  of_property_match_string
- Set DTSEC_ECNTRL_R100M in dtsec_link_up instead of dtsec_mac_config
- Remove rmii/mii properties
- Replace 1000Base... with 1000BASE... to match IEEE capitalization
- Add compatibles for QSGMII PCSs
- Split arm and powerpcs dts updates

Changes in v2:
- Better document how we select which PCS to use in the default case
- Move PCS_LYNX dependency to fman Kconfig
- Remove unused variable slow_10g_if
- Restrict valid link modes based on the phy interface. This is easier
  to set up, and mostly captures what I intended to do the first time.
  We now have a custom validate which restricts half-duplex for some SoCs
  for RGMII, but generally just uses the default phylink validate.
- Configure the SerDes in enable/disable
- Properly implement all ethtool ops and ioctls. These were mostly
  stubbed out just enough to compile last time.
- Convert 10GEC and dTSEC as well
- Fix capitalization of mEMAC in commit messages
- Add nodes for QSGMII PCSs
- Add nodes for QSGMII PCSs
