crypto: arm/aes-neonbs - fix issue with v2.22 and older assembler

The GNU assembler for ARM version 2.22 or older fails to infer the
element size from the vmov instructions, and aborts the build in
the following way;

.../aes-neonbs-core.S: Assembler messages:
.../aes-neonbs-core.S:817: Error: bad type for scalar -- `vmov q1h[1],r10'
.../aes-neonbs-core.S:817: Error: bad type for scalar -- `vmov q1h[0],r9'
.../aes-neonbs-core.S:817: Error: bad type for scalar -- `vmov q1l[1],r8'
.../aes-neonbs-core.S:817: Error: bad type for scalar -- `vmov q1l[0],r7'
.../aes-neonbs-core.S:818: Error: bad type for scalar -- `vmov q2h[1],r10'
.../aes-neonbs-core.S:818: Error: bad type for scalar -- `vmov q2h[0],r9'
.../aes-neonbs-core.S:818: Error: bad type for scalar -- `vmov q2l[1],r8'
.../aes-neonbs-core.S:818: Error: bad type for scalar -- `vmov q2l[0],r7'

Fix this by setting the element size explicitly, by replacing vmov with
vmov.32.
