[PATCH] sha1-avx: use vmovdqa instead of movdqa

[Jussi Kivilinna]

* cipher/sha1-avx-amd64.S: Replace 'movdqa' with 'vmovdqa'.
* cipher/sha1-avx-bmi2-amd64.S: Replace 'movdqa' with 'vmovdqa'.
--

Replace SSE instruction 'movdqa' with AVX instruction 'vmovdqa' as
mixing SSE and AVX instructions can lead to bad performance.
