mb/hp: Add Elitebook 8560w as an HP Sandy/Ivy Bridge laptop variant

The components listed in the documentation work in this port.
The MXM structure of the vendor firmware is added, which is
used by the VGA option ROM with int15h functions.

+# HP EliteBook 8560w
+
+This page describes how to run coreboot on the [HP EliteBook 8560w].

+- EC: please read [HP Laptops with KBC1126 Embedded Controller](hp_kbc1126_laptops)
+
+## Flashing instructions
+
+When running vendor firmware, external flashing is needed.
+
+HP EliteBook 8560w has an 8MiB SOIC-8 flash chip on the bottom of the
+mainboard. You just need to remove the service cover, and use an SOIC-8
+clip to read and flash the chip.
