At xhci removal the USB3 hcd (shared_hcd) is removed before the primary
USB2 hcd. Interrupts for port status changes may still occur for USB3
ports after the shared_hcd is freed, causing NULL pointer dereference.
Check if xhci->shared_hcd is still valid before handing USB3 port events

Ensure that the shared_hcd pointer is valid when calling usb_put_hcd()
The shared_hcd is removed and freed in xhci by first calling
usb_remove_hcd(xhci->shared_hcd), and later
usb_put_hcd(xhci->shared_hcd)

Currently the allocation of a buffer is performed before a sanity check on
the required buffer size and if the buffer size is too large the error exit
return leaks the allocated buffer. Fix this by checking the size before
allocating.
Also, the same buffer is allocated agai

Document r8a7744 xhci support. The driver will use the fallback
compatible string "renesas,rcar-gen2-xhci", therefore no driver

The new scheme is required just to support legacy low and full-speed
devices. For high speed devices, it will slower the enumeration speed.
So in this patch we try the "old" enumeration scheme first for high speed
devices, and this is what Windows does since Windows 8.
