arm64: dts: qcom: sa8295p-adp: Enable the four USB Type-A ports

Browse source 
The multiport USB controller in the SA8295P ADP is connected to four USB
Type-A ports. VBUS for each of these ports are provided by a
TPS2559QWDRCTQ1 regulator, controlled from PMIC GPIOs.

Add the necessary regulators and GPIO configuration to power these.

It seems reasonable that these regulators should be referenced as vbus
supply of usb-a-connector nodes and controlled by e.g. dwc3, but as this
is not supported in Linux today the regulators are left always-on for
now.
