ACPI: thinkpad-acpi: react to Lenovo ThinkPad differences in hot key
Lenovo ThinkPads have a slightly different key map layout from IBM ThinkPads (fn+f2 and fn+f3 are swapped). Knowing which one we are dealing with, we can properly set a few more hot keys up by default. Also, export the correct vendor in the input device, as that information might be useful to userspace.
