The busybox ntpd utility currently uses ntp servers specified in uci.
This patch allows the ntpd utility to use NTP servers received via DHCP(v6)
Following uci parameters have been added:
use_dhcp : enables NTP server config via DHCP(v6)
dhcp_interface : use NTP servers received only on the specified DHCP(v6) interfaces; if empty all interfaces are considered
