USB: Adding #define in hub_configure() and hcd.c file

Browse Source 
This patch is in succession of previous patch
commit c842114792
        xHCI: Adding #define values used for hub descriptor

Hub descriptors characteristics #defines values are added in
hub_configure() in place of magic numbers as asked by Alan Stern.
And the indentation for switch and case is changed to be same.

Some #defines values are added in ch11.h for defining hub class
protocols and used in hub.c and hcd.c in which magic values were
used for hub class protocols.
