[PATCH v3 2/3] phy: qcom: qmp-pcie: Add vdda-refgen supplies for Glymur

The refgen providing reference voltage for PCIe QMP PHY on Glymur requires
two power supplies independent from the PHY's core and qref rails. Add
support for vdda-refgen0p9 and vdda-refgen1p2 supplies with a dedicated
glymur_qmp_phy_vreg_l list.

Update both Gen5x4 and Gen4x2 configurations to use the new supply list.
