[PATCH v7 2/3] xhci: hub: export symbol on xhci_hub_control

[Jim Lin <jilin@nvidia.com>]

XHCI host drivers may override the default xhci_hub_control() with
their own device specific function. To allow these host drivers to
call the xhci_hub_control() function from within their own
hub_control() callback and be built as a module, export the symbol
for xhci_hub_control.
