Subject: [PATCH] arm64: dts: qcom: hamoa-iot-evk: Add vbus regulator support for Type-A ports

The Multiport controller on Hamoa EVK platform is connected to Two 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.
