auxfw_sync: Fix issue of system halt when AUX FW sync is disabled

When AUX FW sync is disabled via GBB flag, it still calls auxfw_finalize
in depthchare and since EC_SYNC is also disabled in depthcharge it halts
the system.

Ideally we should not call depthcharge in case AUX fw sync is disabled via
GBB flag
