Subject: [PATCH 5.2 18/21] crypto: talitos - move struct talitos_edesc into talitos.h

From: Christophe Leroy <christophe.leroy@....fr>

commit d44769e4ccb636e8238adbc151f25467a536711b upstream.

Moves struct talitos_edesc into talitos.h so that it can be used
from any place in talitos.c

It will be required for next patch ("crypto: talitos - fix hash
on SEC1")
