Documentation/acpi: switch example from edge to level interrupts

Configuring touch controllers to use edge-triggered interrupts is not
recommended as it is very easy to lose an edge when kernel drivers
disable the interrupt for one reason or another, and recovering from
this condition requires workarounds in the kernel.

Unfortunately the example setting up a touchpad used edge-triggered
interrupts, and this set up has been propagating through the boards.
Let's switch the example to use level interrupts instead.
