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

* \brief Minimal AHCI-ATA driver

* \author Sebastian Sumpf <Sebastian.Sumpf@genode-labs.com>

|
|
*
|
|
* This driver currently supports only one command slot, one FIS, and one PRD
|
|
* per FIS, thus limiting the request size to 4MB per request. Since the packet
|
|
* interface currently only supports a synchronous mode of operation the above
|
|
* limitations seems reasonable.
