The Armada XP GPIO controller has two ways of notifying interrupts:
using global interrupts or using per-CPU interrupts. In an attempt to
use the best available features, the 'marvell,armadaxp-gpio'
compatible string selects a variant of the gpio-mvebu driver that
makes use of the per-CPU interrupts.

Unfortunately, this doesn't work properly in a SMP context, because we
fall into cases where the GPIO interrupt is enabled on CPU X at the
GPIO controller level, but on CPU Y at the interrupt controller
level. It is not yet clear how to fix that easily.

So for 3.8, our approach is to switch to global interrupts for GPIOs,
so that we do not fall into this per-CPU interrupts problem.

This patch therefore fixes GPIO interrupts on Armada XP
platforms. Without this patch, GPIO interrupts simply do not work
reliably, because their proper operation depends on which CPU the code
requesting the interrupt is running.

We originally thought that the MV78230 variant of the Armada XP had
four Ethernet interfaces, like the other variants MV78260 and
MV78460. In fact, this is not true, and the MV78230 has only three
Ethernet interfaces.

So, the definitions of the Ethernet interfaces is now done as follows:

 * armada-370-xp.dtsi: definitions of the first two interfaces, that
   are common to Armada 370 and Armada XP

 * armada-xp.dtsi: definition of the third interface, common to all
   Armada XP variants.

 * armada-xp-mv78260.dtsi and armada-xp-mv78460.dtsi: definition of
   the fourth interface.

The UART controller used in the Armada 370 and Armada XP SoCs is the
Synopsys DesignWare 8250 (aka Synopsys DesignWare ABP UART). The
improper use of the ns16550 can lead to a kernel oops during boot if
a character is sent to the UART before the initialization of the
driver. The DW APB has an extra interrupt that gets raised when
writing to the LCR when busy. This explains why we need to use
dw-apb-uart driver to handle this.
