wl1251: separate bus i/o code into io.c
In order to eventually support wl1251 spi and sdio interfaces, move the register and memory transfer functions to a common file. Also rename wl1251_spi_mem_{read,write} to indicate its common usage. We still use spi_read internally until SDIO interface is introduced so nothing functional should change here.
