Helios64 tweak (#2186)

* bsp: helios64: Add fancontrol

- Fancontrol configuration
- Udev rules for fan and temp sensor

Signed-off-by: Aditya Prayoga <aditya@kobol.io>

* bsp: helios64: Enable heartbeat on system status led

The reason systemd service used instead of device tree modification, is
to give visual notification that the system is ready.

Signed-off-by: Aditya Prayoga <aditya@kobol.io>

* armbian-hardware-optimization: SATA & 2.5GbE IRQ pinning on Helios64

- 2.5GbE USB LAN which is attached to XHCI, assigned to CPU4
- SATA controller assigned to CPU4 and CPU5
