[RESEND x2][PATCH v2] phy: qcom-qusb2: Re add "qcom,sdm845-qusb2-phy" compat string

[John Stultz]

This patch fixes a regression in 5.7-rc1+

In commit 8fe75cd4cddf ("phy: qcom-qusb2: Add generic QUSB2 V2
PHY support"), the change was made to add "qcom,qusb2-v2-phy"
as a generic compat string. However the change also removed
the "qcom,sdm845-qusb2-phy" compat string, which is documented
in the binding and already in use.

This patch re-adds the "qcom,sdm845-qusb2-phy" compat string
which allows the driver to continue to work with existing dts
entries such as found on the db845c.
