Revert "ARM: dts: armada-38x: Fix compatible string for gpios"
This reverts commit c4de4667f15d04ef5920bacf41e514ec7d1ef03d, which causes a regression on Turris Omnia (Armada 385): GPIO interrupts cease to work, ending up in the DSA switch being non-functional. The blamed commit is incorrect in the first place: If compatible = "marvell,armadaxp-gpio", the second (address, size) pair of the reg property must to point to the per-CPU interrupt registers <0x18800 0x30> / <0x18840 0x30>, and not to the blink enable registers <0x181c0 0x08> / <0x181c8 0x08>. But even fixing that leaves the GPIO interrupts broken on the Omnia. Furthermore: Commit 5f79c651e81e explains very well, why the gpio-mvebu driver does not work reliably with per-CPU interrupts. Commit 988c8c0cd04d deprecates compatible = marvell,armadaxp-gpio for this reason.
