To let the xhci driver support USB offload, add hooks for vendor to have
customized behavior for the initialization, memory allocation, irq work, and
device context synchronization. Detail is in each patch commit message.

Is this related to the usb audio sideband capability that was added to the xHCI specification?
If yes, then we should probably implement the generic parts first, and then add
the vendor specific hooks.

This is for offloading, no matter what type of offloading.
I made the hooks generically and can be used for usb audio on the xhci
which is not including the usb audio sideband capability.
