The TUSB73x0 is a USB 3.0 xHCI Host Controller Hub using a PCIe x1 Gen2
interface. The TUSB7320 supports up to two downstream ports, and the
TUSB7340 supports up to four. It includes a feature to configure the
polarity of the PWRONx# signals, which are used to control other peripherals.
In some systems, the default polarity needs to be inverted, which is
supported by the hardware through software configuration. This patch
series introduces TUSB73x0 PCIe device tree bindings and modifies the
USB XHCI PCI driver to handle PWRONx# polarity via a device tree property.

v2:
 - Change the property type from bool to flag
 - Rename the property as ti,tusb7320-pwron-active-high
