arm64: dts: qcom: sda660-ifc6560: document missing USB PHY supplies

Browse Source 
On the IFC6560 one of the USB PHY supplies is the L10A power supply.
However this regulator also supplies VDDA_APC1_CS, VDD_PLL2 and VDD_P11
consumers. Touching the supply causes the board to be reset. Document
the supply as a fixed always-on regulator.
