Hung-Te Lin 85ecdb1471 mmio: Fix failure in bit field macro when accessing >30 bits 
For 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'".

And for bit fields with 32 bits (e.g: DEFINE_BITFIELD(MYREG, 31, 0) ),
the error will be:
 "error: left shift count >= width of type [-Werror=shift-count-overflow]"

To fix these issues, the bit field macros should always use unsigned
integers, and use 64bit integer when creating mask value.
