ntp: make servers configurable and default to none configured
People can't blindly use pool.ntp.org, especially if they are building for a product or something that could be used in a product, so at least try to get people to do the right thing and not use pool.ntp.org by default. The previous network interface up script is now installed as ntpdate-sync in ${bindir} (and symlinked as the network if-up script). NTPSERVERS needs to be set in /etc/default/ntpdate.default at runtime, or a different version of this file with a default value can be provided in a bbappend. (If you intend to use ntpd you will also want to provide an ntp.conf with the appropriate server(s) set there as well.) Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com>
