wl1271: Change wl12xx Files Names
All files name prefix removed due to the fact that wl12xx driver supports wl1271 and wl1273. Also the definition in Kconfig and header files changed respectively. Signed-off-by: Shahar Levi <shahar_levi@ti.com> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>
