From: Qiang Yu <quic_qianyu at quicinc.com>

Enable the pwrctrl driver, which is utilized to manage the power supplies
of the devices connected to the PCI slots. This ensures that the voltage
rails of the standard PCI slots on some platforms eg. X1E80100-QCP can be
correctly turned on/off if they are described under PCIe port device tree
node.
