wlcore: Propagate errors from wl1271_raw_read32
Propagate errors from wl1271_raw_read32. Since the read functions had no way of returning errors in-band, change their prototypes. Also rename prefixes of wlcore functions which their prototypes had to be changed. Signed-off-by: Ido Yariv <ido@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
