mb/google/rambi: Remove touchscreen as ACPI wake device

Users report having the touchscreen as a wake device causes many
spurious wakeups due to proximity to the keyboard when the lid is
closed, so remove it as a wake source.

TEST=build/boot google/glimmer, observe no unintended wakeups when
the lid is closed.
