mfd: stmpe: Get rid of irq_invert_polarity
Since the very first patch, stmpe core driver is using irq_invert_polarity as part of platform data. But, nobody is actually using it in kernel till now. Also, this is not something part of hardware specs, but is included to cater some board mistakes or quirks. So, better get rid of it.
