wifi: wilc1000: Fold chip_allow_sleep()/chip_wakeup() into wlan.c

Neither chip_allow_sleep()/chip_wakeup() is used outside of wlan.c .
Make both functions static and remove both the exported symbol and
entries from wlan.h .

Make chip_allow_sleep() return error code in preparation for the
follow up patches.

Move acquire_bus() and release_bus() to avoid forward declaration
of chip_allow_sleep()/chip_wakeup().
