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.
