Jason Wang 477f719714 vdpa_sim_net: support feature provisioning
This patch implements features provisioning for vdpa_sim_net.

1) validating the provisioned features to be a subset of the parent
   features.
2) clearing the features that is not wanted by the userspace

For example:

vdpasim_net:
  supported_classes net
  max_supported_vqs 3
  dev_features MTU MAC CTRL_VQ CTRL_MAC_ADDR ANY_LAYOUT VERSION_1 ACCESS_PLATFORM

1) provision vDPA device with all features that are supported by the
   net simulator

dev1: mac 00:00:00:00:00:00 link up link_announce false mtu 1500
  negotiated_features MTU MAC CTRL_VQ CTRL_MAC_ADDR VERSION_1 ACCESS_PLATFORM

2) provision vDPA device with a subset of the features

dev1: mac 00:00:00:00:00:00 link up link_announce false mtu 1500
  negotiated_features CTRL_VQ VERSION_1 ACCESS_PLATFORM
