[00/43] phy: qcom,qmp: fix dt-bindings and deprecate lane suffix

Message

When adding support for SC8280XP to the QMP PHY driver I noticed that
the PHY provider child node was not described by the current DT schema.

The SC8280XP PHYs also need a second fixed-divider PIPE clock
("pipediv2") and I didn't want to have to add a bogus "lane" suffix to
the clock name just to match the current "pipe0" name so I decided to
deprecate the unnecessary suffix in the current binding instead.

To be able to add the missing child-node schema and handle device
specifics like additional PIPE clocks, it quickly became obvious that
the binding needs to be split up.

This series fixes some issue with the current schema before splitting
it up in separate schemas for PCIe, UFS and USB, which are then cleaned
up further before adding missing parts like the child PHY provider
nodes and examples.

The MSM8996 PCIe PHY gets its own schema as this is the only non-combo
PHY that actually provides more than one PHY per IP block. Note that the
"lane" suffix is still unnecessary and misleading.

The final patches adds support for the new resource names to the
(recently split up) PHY drivers. Included is also a related combo PHY
cleanup.

I'll post a separate series with related DTS fixes caught while
developing this series.
