arm64: dts: qcom: qcm6490-fairphone-fp5: Enable UFS

Browse Source 
Enable the UFS phy and controller so that we can access the internal
storage of the phone.

At the same time we need to bump the minimum voltage used for UFS VCC,
otherwise it doesn't initialize properly. The 2.952V is taken from the
vcc-voltage-level property downstream.

See also the following link for more information about the VCCQ/VCCQ2:
