In case of a DT-based probe of the stmpe MFD driver, the irq_gpio was zero, which resulted in the driver failing to probe.
Implement DT properties "irq-over-gpio" and "irq-gpios" which are already used in "arch/arm/boot/dts/spear320-hmi.dts" to circumvent these problems. The new behaviour is the expected one and copies the behavior of platform_data-based probe.
