phy: qcom-qmp-pcie-msm8996: drop reset lane suffix

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

Update driver to support the new binding where the "lane" reset name has
been deprecated by instead requesting the reset by index.
