[PATCH v6 4/4] ARM: dts: armada-xp: Use pwm-fan rather than gpio-fan

[Ralph Sennhauser <ralph.sennhauser@xxxxxxxxx>]

From: Andrew Lunn <andrew@xxxxxxx>

The mvebu GPIO driver can also perform PWM on some pins. Use the pwm-fan
driver to control the fan of the WRT1900AC, giving us finer grained control
over its speed and hence noise.
