phy: qcom-qmp-usb: drop pipe clock lane suffix

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.

Update driver to support the new binding where the pipe clock name has
been deprecated by instead requesting the clock by index.
