xHCI: Adding #define values used for hub descriptor
xhci-hub used some numerical values for initialisation of root hub descriptors. #define values are addded in usb 2.0 hub specification file and these values are used for root hub characteristics initialisation. Also use some #defines in places where magic numbers are being used.
