mb/google/skyrim/baseboard/devicetree: enable mp2 device
The mp2 PCI device is still present when no mp2 firmware is loaded. When this device isn't explicitly enabled in the mainboard's devicetree, the chipset devicetree default of the device being disabled is used. This results in coreboot's resource allocator not allocating resources to the device and since the bridge doesn't have enough MMIO space reserved, the Linux kernel can't assign resources to it. To fix this problem, enable the mp2 device in the mainboard's devicetree so that it gets its resources assigned by coreboot. An equivalent change was verified on Chausie.
