crypto: arm/ghash-ce - add missing async import/export
Since commit 8996eafdcbad ("crypto: ahash - ensure statesize is non-zero"),
all ahash drivers are required to implement import()/export(), and must have
a non-zero statesize. Fix this for the ARM Crypto Extensions GHASH
implementation.
Fixes: 8996eafdcbad ("crypto: ahash - ensure statesize is non-zero")
