Bob Copeland 0d77e14133 wl1251: make wl1251_set_partition bus agnostic
The same partition setting code can be used for both SPI and SDIO
modes, if we remove the spi-specific commands and use the more
generic buffer write routines.  Do that and move it to io.c
since it deals with register/memory address offsets.
