Subject: crypto: arm64/sha1-ce - fix for big endian

From: Ard Biesheuvel <ard.biesheuvel@linaro.org>

commit ee71e5f1e7d25543ee63a80451871f8985b8d431 upstream.

The SHA1 digest is an array of 5 32-bit quantities, so we should refer
to them as such in order for this code to work correctly when built for
big endian. So replace 16 byte scalar loads and stores with 4x4 vector
ones where appropriate.
