[PATCH 43/43] phy: qcom-qmp-usb: drop pipe clock lane suffix

[Johan Hovold]

The pipe clock is defined in the "lane" node so there's no need to keep
adding a redundant lane-number suffix to the clock name.

Drop the lane suffix from the pipe clock name, but continue supporting
the legacy name as a fall back.
