configs: Move CONFIG_PROVE_LOCKING from linaro-base.conf to debug.conf
CONFIG_PROVE_LOCKING is an expensive option which adds significant overhead to lock operations. The examples are 5% power consumption increase for vexpress with this option enabled, and improving netperf on the loopback results by ~200% after disabling DEBUG_MUTEXES (DEBUG_MUTEXES is selected by PROVE_LOCKING). Move CONFIG_PROVE_LOCKING to a separate debug.conf fragment, so that it could be enabled only when it is needed. Signed-off-by: Andrey Konovalov <andrey.konovalov@linaro.org>
