vlandev: support setting ingress/egress QoS mappings

It allows setting mappings for instance this way:
"""
config device
  option name 'vlan41'
  option type '8021q'
  option vid '41'
  option ifname 'eth1'
  list   ingress_qos_mapping '1:2'
  list   ingress_qos_mapping '2:5'
  list   egress_qos_mapping '0:3'
"""
