Revert "ARM: dts: armada-38x: Fix compatible string for gpios"

This reverts commit c4de466, 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 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.
