Add the required properties to the GPIO nodes for them to be used as PWM
lines.

Hi everyone,
this patch uses "marvell,armada-370-gpio" for the compatible property
and as such depends on the rename of the property to still make it in in
time for 4.12 ("gpio: mvebu: change compatible string for PWM support").
Otherwise the compatible string will need to be amended to
"marvell,armada-370-xp-gpio".
Checked the functional spec and the register ranges and offsets are the
same as for armada-xp. Likely the same holds true for the armada-39x
family, though I neither have access to the spec nor any such hardware.
Ralph
