Subject: arm64: dts: rockchip: Add support for two PWM fans on
helios64
Origin: https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git/patch/?id=271b66414df0b172c936b3cfd1894b7939f84165
On the helios64 board the two connectors P6 and P7 are supposed to
power two fans. Add the corresponding pwm-fan devices.
