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 clean up and fixes some issue with the current schema before
splitting it up in separate schemas for PCIe, UFS and USB and adding
missing parts like the child PHY provider nodes.

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 add support for the updated binding to the (recently
split up) PHY drivers. Included is also a related combo PHY cleanup.
This fails at patch 2 for me on v6.0-rc1, please rebase and resend
Are you sure you haven't applied anything to your local tree that causes
this?

I just tried fetching the v3 series from lore and it applies just fine
on top of 6.0-rc1.

Note that if you've added a new compatible string locally, the second
patch which sorts the compatible strings is likely to fail to apply.
