arm64: dts: qcom: sc7180-trogdor: Simplify trackpad enabling

Trogdor boards with a detachable keyboard don't have a trackpad over
i2c. Instead the trackpad is on the detachable keyboard base. Let's move
the enabling of the trackpad i2c bus out of the base sc7180-trogdor.dtsi
file so that each trogdor board that is detachable, of which there are
many, doesn't have to disable the trackpad bus.
