This patch adds USB HOST register definitions. The definition for EHCI INSNREG00 regiser and corresponding bit field definitions are added.

As per the definition of bit-fields in other registers, it would be good to prepend the complete register name before the bit-field defines. EHCI_INSNREG00_ENA_INCR16 ... Considering the similarity of this patchset with the earlier patchset from Sangwook, IMO, it would be appropriate to give him due credit in both these patches.
