[PATCH v2 2/2] Revert "ARM: dts: armada-39x: Fix compatible string for gpios"

This reverts commit d10886a4e6f85ee18d47a1066a52168461370ded.

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 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.

v1->v2: Be more explicit about the reg property.
