USB: Adding #define in hub_configure() and hcd.c file
This patch is in succession of previous patch commit c8421147926fcacf53081a36438a0bed394da9f5 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.
