xhci: Refactor bus suspend state into a struct.
There are several variables in the xhci_hcd structure that are related to
bus suspend and resume state. There are a couple different port status
arrays that are accessed by port index. Move those variables into a
separate structure, xhci_bus_state. Stash that structure in xhci_hcd.
When we have two roothhubs that can be suspended and resumed separately,
we can have two xhci_bus_states, and index into the port arrays in each
structure with the fake roothub port index (not the real hardware port
index).
