[PATCH 01/16] crypto: authenc - Don't multiply priorities

[Steffen Klassert <steffen.klassert@secunet.com>]

Most crypto algorithms simply take the priority value of the underlying
algorithm and add some value to calculate the algorithms priority.
The only exeptions are the authenc algorithms. We change the authenc
algorithms to calculate their priority to the sum of the underlying
algorithms plus 100. With this we can keep the priority consistent if
one of the underlying algorithms changes the priority.
