USB: asix - Add AX88178 support and many other changes

* More generi-fication of function/macro names where appropriate:
     ax88772_xx() -> asix_xx()

* Reorder functions to provide more logical grouping

* AX88178 device support

* Support DLink DUB-E100 Rev B Support

* Hopefully resolve all endian-ness issues

* Use more defines for bitmask values

* Change a number of devdbg() calls to deverr() so that if DEBUG is not
  defined, the error messages still get through as necessary
