gpio: mvebu: change compatible string for PWM support
As it turns out more than just Armada 370 and XP support using GPIO lines as PWM lines. For example the Armada 38x family has the same hardware support. As such "marvell,armada-370-xp-gpio" for the compatible string is a misnomer. Change the compatible string to "marvell,armada-370-gpio" before the driver makes it out of the -rc stage. This also follows the practice of using only the first device family supported as part of the name. Also update the documentation and comments in the code accordingly.
