Blackfin: fix addr type with bfin_write_{or,and} helpers
Since the bfin_write() func needs proper type information in order to
expand into the right bfin_writeX() variant, preserve the addr's type
when setting up the local __addr. Otherwise the helpers will detect
the variant based upon sizeof(void) which is almost never right.
