x86: Restore reboot quirks by DMI, fix reboot on a number of systems
The following patch ports the functionality following changeset from
Linux (from 2008) to xen:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=14d7ca5c
It implements an additional reboot quirk to do a PCI reset via port
CF9.
This also restores some code dropped in the x86_32 target removal
(changeset 5d1181a5ea5e0f11d481a94b16ed00d883f9726e) which sets some
quirks based on DMI matching.
This will add reboot quirks on the following systems that are known to
be necessary on Linux:
Dell E520
Dell PowerEdge 1300
Dell PowerEdge 300
Dell OptiPlex 745
Dell OptiPlex 745
Dell OptiPlex 745
Dell OptiPlex 330
Dell OptiPlex 360
Dell OptiPlex 760
Dell PowerEdge 2400
Dell Precision T5400
Dell Precision T7400
HP Compaq Laptop
Dell XPS710
Dell DXP061
Sony VGN-Z540N
ASUS P4S800
Acer Aspire One A110
Apple MacBook5
Apple MacBookPro5
Apple Macmini3,1
Apple iMac9,1
Dell Latitude E6320
Dell Latitude E5420
Dell Latitude E6220
Dell Latitude E6420
Dell OptiPlex 990
Dell OptiPlex 990
Dell Latitude E6520
Dell OptiPlex 790
Dell OptiPlex 990
Dell OptiPlex 390
Dell Latitude E6320
Dell Latitude E6420
Dell Latitude E6520
I clearly have not been able to test on all of these systems.
It does fix rebooting on the Dell 790, and should *not* change the
reboot paths of systems not on this DMI match list.

Use driver_data, thus requiring only a single handler function.
