This adds the missing interrupt transfer support to xHCI driver, so that devices like USB keyboard that uses interrupt transfer when CONFIG_SYS_USB_EVENT_POLL is defined can work.
This also adds full speed device support. Unlike low/high/super speed devices, full speed device may report its endpoint 0 max packet size as 8/16/32/64. xHCI driver guesses 64 for the first attempt to get the initial 8 bytes device descriptor, and later adjusts the context for endpoint 0. This series also made several updates to xHCI driver to conform with the spec. This series is available at u-boot-x86/xhci-working for testing.
