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.
Signed-off-by: Klaus Kudielka <klaus.kudielka@gmail.com> --- v1->v2: Be more explicit about the reg property.
