[PATCH v4 2/3] dt-bindings: gpio: gpio-mvebu: deprecate armadaxp-gpio

[Chris Packham <chris.packham@alliedtelesis.co.nz>]

Commit 5f79c651e81e ("arm: mvebu: use global interrupts for GPIOs on
Armada XP") the marvell,armadaxp-gpio compatible obsolete.

The driver code still exists to handle the armadaxp behaviour but all
the in-tree boards use the marvell,armada-370-gpio.  Document the
marvell,armadaxp-gpio compatible as deprecated.

Notes:
    This could potentially be squashed into the first commit but it seemed
    more proper to do a straight 1:1 conversion of the old binding then
    clean things up to match reality.
