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.

Implement connector nodes to embed the vbus supply within them. Since
there is no entity currently that can read vbus supply from a Type-A
connector and control it, mark the supplies as always on.

Changes in v3:
- Added connector-a nodes and embedded vbus supply in them
- Added RB Tag of Konrad from internal review after adding connector nodes
