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.

The Hana device has a second source option trackpad, but it is missing
its regulator supply. It only works because the regulator is marked as
always-on.
Add the regulator supply, but leave out the post-power-on delay. Instead,
document the post-power-on delay along with the reason for not adding
it in a comment.

as interrupts-extended where possible across all MT8173 DTs to both
simplify and reduce code size.
