Subject: [PATCH] platform/surface: gpe: Add support for 15" Intel version of Surface Laptop 3

In addition to a 13" version, there is also a 15" (business) version of
the Surface Laptop 3 based on Intel CPUs. This version also handles
wakeup by lid via (unmarked) GPEs, so add support for it as well.
