MLK-19365: crypto: gcm: Cache aligned auth_data

Generic GCM is likely to end up using a hardware accelerator to do
part of the job. Allocating hash, iv and result in a contiguous memory
area increases the risk of dma mapping multiple ranges on the same
cacheline. Also having dma and cpu written data on the same cacheline
will cause coherence issues.

MLK-19365: drivers: crypto: caamalg: ecb(aes) does not use IV

The crypto template lrw(crypto/lrw.c) and xts(crypto/xts.c) require
an ecb(aes) algo as base which ivsize must be zero as ecb(aes)
doesn't need an IV.

The patch 84f5e22194 "MA-9807: Fix ecb(aes) use without an IV"
add support in caamalg for ecb(aes) without iv.

The ecb(aes) implementation of the CAAM declare an ivsize which is
against specification. So remove it to be usable with cryto templates.
