mfd: stmpe: add ADC block resources
In order to use the auxiliar ADC inputs of STMPE811 devices we need to add resources for the ADC block. Also move the ADC macros from the touchscreen driver to the general header file. We will need them for the ADC driver in future. Conflicts: drivers/mfd/stmpe.c
