Change interface to board controller to match Rev. 2 hardware, HYP-7965

In Rev. 2 the interface of the board controller has changed from
/dev/serial/by-path/platform-orion-ehci.0-usb-0:1.4:1.1-port0
to
/dev/serial/by-path/platform-orion-ehci.0-usb-0:1.4:1.0-port0

Hipos services depending on this (hipos-device-info, hipos-network-setup,
hipos-time, hipos-watchdog) have been modified accordingly.
