The code in the current implementation of safexcel_hmac_alg_setkey
can be reused by safexcel_cipher. This patch does just that by
renaming the previous safexcel_hmac_setkey to __safexcel_hmac_setkey.
The now-shared safexcel_hmac_alg_setkey becomes safexcel_hmac_setkey
and a new safexcel_hmac_alg_setkey has been added for use by ahash
transforms.
As a result safexcel_aead_setkey's stack frame has been reduced by
about half in size, or about 512 bytes.

The OCE normally requires initialization and dedicated firmware, but
for the simple operations supported by this driver, we just bypass it

On systems with coherence issues, packet processed could succeed while
it should have failed, e.g. because of an authentication fail.
This is because the driver would read stale status information that had
all error bits initialised to zero = no error.
Since this is potential a security risk, we want to prevent it from being
a possibility at all. So initialize all error bits to error state, so
that reading stale status information will always result in errors.
