arm64: dts: mediatek: mt8186-steelix: Mark second source components for probing

Browse Source 
Steelix design has two possible trackpad component sources. Currently
they are all marked as available, along with having workarounds for
shared pinctrl muxing and GPIOs.

Instead, mark them all as "fail-needs-probe" and have the implementation
try to probe which one is present.

Also remove the shared resource workaround by moving the pinctrl entry
for the trackpad interrupt line back into the individual trackpad nodes.
