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.

I'd ask for the DTSI patch too...
