xhci: refactor static MSI-X function

Browse source

The current way the xhci driver sets up MSI/MSI-X interrupts is overly
complex and messy. The whole MSI/MSI-X setup can be done in one simple
function.

Start refactoring this by incorporating 'xhci_setup_msix()' into
'xhci_try_enable_msi()'. 'xhci_setup_msix()' is a static function which
is only called by 'xhci_try_enable_msi()'.
