[dts] [v2] support dpdk2.0 code

[huilongx xu <huilongx.xu@intel.com>]

From: huilong xu <huilongx.xu@intel.com>

changed list:
    1. when start testpmd by pmd_output model, if testpmd parameter not include
       "--txqflags=0", add it. because in dpdk2.0 testpmd must used txqflags for
       open hardware features, egg: checsum offload, vlan
    2. pmd_output add a function set_default_corelist, if the server cores number more then 2, the default cores is 2. In test case you can used "Default"
       to start testpmd.
