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.
