usb: host: xhci-plat: add support for the Armada 375/38x XHCI controllers
The Armada 375 and 38x SoCs come with an XHCI controller that requires some specific initialization related to the MBus windows configuration. This patch adds the support for this special configuration as an XHCI quirk executed during probe. Two new compatible strings are added to identify the Armada 375 and Armada 38x XHCI controllers, and therefore enable the relevant quirk.
