[PATCH v4 02/15] crypto: ti - Fix spinlock inconsistency in DTHEv2

Probe and remove functions use spin_(un)lock for acquiring the
dthe_dev_list.lock. But dthe_get_dev uses the bh variant. Change
spin_(un)lock_bh to spin_(un)lock to avoid potential deadlock when a
softIRQ process tries to acquire the already held lock.
