Revert "ARM: dts: armada-39x: Fix compatible string for gpios"

This reverts commit d10886a.

If compatible = "marvell,armadaxp-gpio", the reg property requires a
second (address, size) pair, which points to the per-CPU interrupt
registers <0x18800 0x30> / <0x18840 0x30>.

Furthermore:
Commit 5f79c65 explains very well, why the gpio-mvebu driver does not
work reliably with per-CPU interrupts.
Commit 988c8c0 deprecates compatible = marvell,armadaxp-gpio for this
reason.
