Subject: [PATCH] crypto: sun4i-ss: add missing statesize

sun4i-ss implementaton of md5/sha1 is via ahash algorithms.
Commit 8996eafdcbad ("crypto: ahash - ensure statesize is non-zero")
made impossible to load them without giving statesize. This patch
specifiy statesize for sha1 and md5.

Fixes: 6298e948215f ("crypto: sunxi-ss - Add Allwinner Security System crypto accelerator")
Cc: <stable@...r.kernel.org> # v4.3+
Tested-by: Chen-Yu Tsai <wens@...e.org>
