linux-4.14.13: Build out of tree aacraid module

Thomas reports the problem below [1].

> further testing of the stock aacraid-driver yielded some deficits in
> the sys-fs representation. Aparently it doesn't link the disk devices
> to enclosure slots, a thing that the off-tree microsemi driver does
> (and the LSI driver also, so i deem it's 'good-practice' in modern HBA
> drivers). Indeed it doesn't affect the functionality, but it hampers
> maintenance and client-tools a bit more than just a bit.

> Here is the location info of the missing sys-fs parts
> short way, where as the `device` part is missing:
