[PATCH] ucc_geth: changes to ucc_geth driver as a result of qe_lib changes and bugfixes

changes due to qe_lib changes include:

o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
  QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
  BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
  because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments

bugfixes, courtesy of Scott Wood, include:

- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
  device_is_compatible() will only compare up to the length of the
  test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c.  The old code was overwriting and dereferencing random stack contents.
