usb: xhci: Fix suspend/resume when used with OTG core
In the OTG case, the controller might not yet have been
added or is removed before the system suspends.
Assign xhci->main_hcd during probe to prevent NULL
pointer de-reference in xhci_suspend/resume().
Use the hcd->state flag to check if HCD is halted
and if that is so do nothing for xhci_suspend/resume().
[Only for xhci-plat devices, pci devices need it in gen_setup -Mathias]
