mmio: Use unsigned integers for bit operations

When declaring bit fields with 31 bits (e.g:
 DEFINE_BITFIELD(MYREG, 30, 0) ), the calculation of mask value
will go overflow:
 "error: integer overflow in expression '-2147483648 - 1' of
  type 'int' results in '2147483647'").

To fix that, the bit field macros should always use unsigned
integers.
