This converts the mrvl-gpio binding to DT schema format using json-schema. Various fixes were done during the conversion, such as adding more properties that are in fact mandatory or extending the examples to include child nodes with extra GPIO blocks. The compatible strings are a mess. It is not clear why so many of them are needed; the driver doesn't really seem to differentiate between the models. Some of them, like marvell,pxa93x-gpio and marvell,pxa1928-gpio are not used at all, so it's not known how many interrupts they utilize. On the other hand, mrvl,pxa-gpio has been seen in the tree, but it doesn't end up in any actual DTB file. In any case -- the schema merely copies whatever was in the original binding document, so it's hopefully no more wrong that the original.
