[dts] [PATCH v2] framework: wait 10 seconds after testpmd starts to ensure link is up

[Herbert Guan <herbert.guan@arm.com>]

It'll take some time for links up after testpmd is started.
Before that "testpmd>" will be prompted but test shall not start
until links are up.  "LSC event" is a better checker for a specific
test case.  While since pmd_output.py is usd by many test cases, wait
10 seconds will be safer, in case of some test cases do not actually
expect for an established link.
