Instead of having them all available, 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.

Changes since v4:
- Rebased
Changes since v3:
- Also remove second source workaround, i.e. move the interrupt line
pinctrl entry from the i2c node back to the components.
Changes since v2:
- Drop class from status
