wl1251: fix ELP_CTRL register accesses when using SDIO
For some unknown reason ELP_CTRL can't be accesed using
sdio_memcpy_* functions (any attemts to do so result in timeouts):
wl1251: ERROR sdio write failed (-110)
wl1251: ERROR sdio read failed (-110)
wl1251: WARNING WLAN not ready
To fix this, add special IO functions for ELP_CTRL access that are
using sdio_readb/sdio_writeb. Similar handling is done in TI
reference driver from Android code drop.
