This adds serdes support to the LS1088ARDB. I have tested the QSGMII
ports as well as the two 10G ports. Linux hangs around when the serdes
is initialized if the si5341 is enabled with the in-tree driver, so I
have modeled it as a two fixed clocks instead.
To enable serdes support, the DPC needs to set the macs to
MAC_LINK_TYPE_BACKPLANE. All MACs using the same QSGMII should be
converted at once. Additionally, in order to change interface types, the
MC firmware must support DPAA2_MAC_FEATURE_PROTOCOL_CHANGE.

(no changes since v13)
Changes in v13:
- Split off interrupt and SFP changes into separate commits
Changes in v10:
- Move serdes bindings to SoC dtsi
- Use "descriptions" instead of "bindings"
- Don't use /clocks
- Add missing gpio-controller properties
Changes in v9:
- Add fsl,unused-lanes-reserved to allow a gradual transition, depending
on the mac link type.
- Remove unused clocks
- Fix some phy mode node names
- phy-type -> fsl,phy
Changes in v8:
- Rename serdes phy handles like the LS1046A
- Add SFP slot binding
- Fix incorrect lane ordering (it's backwards on the LS1088A just like it is in
the LS1046A).
- Fix duplicated lane 2 (it should have been lane 3).
- Fix incorrectly-documented value for XFI1.
- Remove interrupt for aquantia phy. It never fired for whatever reason,
preventing the link from coming up.
- Add GPIOs for QIXIS FPGA.
- Enable MAC1 PCS
- Remove si5341 binding
Changes in v4:
- Convert to new bindings
