PCI: starfive: Use regulator APIs to control the 3v3 power supply of PCIe slots
The driver has been using the "enable-gpios" property to control the 3v3
power supply of PCIe slots. But it is not documented in the dt-bindings and
also using GPIO APIs is not a standard way to control PCIe slot power, so
use the documented "vpcie3v3-supply" property and regulator APIs to control
the slot supply.
This change will break the DTs which used "enable-gpio" or "enable-gpios"
property under the controller node. Since these properties were not defined
in the bindings, it is safe to switch to "vpcie3v3-supply". Any out-of-tree
DTS impacted by this change should migrate to "vpcie3v3-supply" instead.
