From: Raveendra Padasalagi <raveendra.padasalagi@broadcom.com>

[ Upstream commit 4f0129d13e69bad0363fd75553fb22897b32c379 ]

Remove setkey() callback handler for normal/non key
hash algorithms and keep it for AES-CBC/CMAC which needs key.

Fixes: 9d12ba86f818 ("crypto: brcm - Add Broadcom SPU driver")
