Multiport USB controller (host-only) of SA8295 ADP has 4 Type-A ports exposed for connecting peripherals. The VBUS to these peripherals is provided by TPS2559QWDRCTQ1 regulators connected to these ports. Each regulator has an enable pin controlled by PMM8540. Since these regulators are GPIO controlled regulators, model them as fixed regulators and keep them Always-On at boot since we are wakeup capable and we don't need to turn them off on suspend. Also since we don't enter device mode, these regulators can be kept on.
