When the STMPE IRQ is triggered to be active high level-sensitive, the
Nomadik GPIO controller it uses complains, although it still works.
Recently we attempted to move triggering to low-to-high in an attempt
to prevent the warning; however, this ensured that the IRQ was actually
missed completely. Now we have a solution which both works and keeps the
GPIO controller happy.
