qcacmn: Add QDF type to define a bitmap based on bits size

The bitmaps used in the driver are defined either as a single
or array of unsigned longs or some other types.

The bitmap variable size is different based on the platform(32/64 bit),
for unsigned long types.

Add support to have a platform agnostic consistent bitmap size
using the Linux provided interface for defining bitmaps.
