Subject: [PATCH] x86: Add quirk to make Apple MacBookPro5,1 use reboot=pci

MacBookPro5,1 is not able to reboot unless reboot=pci is set.
This patch forces it through a DMI quirk specific to this device.

Seen that the previous quirk by Paul Mackerras was committed to tip/x86/urgent,
this is based on top of that patch which introduced the reboot=p quirk stuff.
