[PATCH 9/9] mfd: sec-irq: Do not enforce (incorrect) interrupt trigger type

[Krzysztof Kozlowski]

Interrupt line can be configured on different hardware in different way,
even inverted.  Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.

The Samsung PMIC drivers are used only on Devicetree boards.

Additionally, the PMIC datasheets describe the interrupt line as active
low with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.

This patch should wait till DTS changes are merged, as it relies on
proper Devicetree.
