mb/google/myst: 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. Enable the mp2 device in
the mainboard's devicetree so that it gets its resources assigned by
coreboot.
