ahci: avoid to reinstantiate backend driver 

Instead of fixing the missing dynamic facilities of the AHCI driver
backends for x86 and Exynos5, just avoid to create/destroy the backend
for every new connection, but always use one and the same object.
The AHCI drivers need to be re-written anyway, see issue #1352 for instance,
we can make it more robust for the dynamic case then.

Fixes #786
Fixes #1133
