dm: remove some dynamic parameters from acrn-dm usage

The following parameters have not used by new design:

1.  --vsbl <vsbl_file_path>
2.  --part_info <part_info_name>
3.  -G, --gvtargs <GVT_args>
4.  -s <slot>,pci-gvt
5.  -Y, --mptgen
6.  -s <slot>,virtio-hdcp
7.  -s <slot>,npk
8.  -s <slot>,virtio-coreu
9.  -i, --ioc_node <ioc_mediator_parameters>
10. --pm_by_vuart [pty|tty],<node_path>
11. --pm_notify_channel <channel>

This patch remove these parameters from usage and comment in code to
explain they are all obsoleted now.
