[PATCH v2 2/7] crypto: ti - Fix potential deadlock bug in DTHEv2

[T Pratham]

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.

Fixes: 52f641bc63a46 ("crypto: ti - Add driver for DTHE V2 AES Engine (ECB, CBC)")
