mb/google/poppy/nami: Add 'detect' flag for Elan touchpad

Add the 'detect' flag to the Elan touchpad, so coreboot can determine
which touchpad type is present at runtime and generate the correct
ACPI entry for it (the Synaptics touchpad already has the flag).

Test: build/boot google/nami, verify touchpad works under Linux/Windows
