Input: stmpe-keypad - add support for Device Tree bindings
This patch allows the STMPE driver to be successfully probed and initialised when Device Tree support is enabled. Besides the usual platform data changes, we also separate the process of filling in the 'in use' pin bitmap, as we have to extract the information from Device Tree in the DT boot case.
