devlink: Add resource scope filtering to resource dump

Browse Source 
Allow filtering the resource dump to device-level or port-level
resources using the 'scope' option.

Example - dump only device-level resources:

  $ devlink resource show scope dev
  pci/0000:03:00.0:
    name max_local_SFs size 128 unit entry dpipe_tables none
    name max_external_SFs size 128 unit entry dpipe_tables none
  pci/0000:03:00.1:
    name max_local_SFs size 128 unit entry dpipe_tables none
    name max_external_SFs size 128 unit entry dpipe_tables none

Example - dump only port-level resources:

  $ devlink resource show scope port
  pci/0000:03:00.0/196608:
    name max_SFs size 128 unit entry dpipe_tables none
  pci/0000:03:00.0/196609:
    name max_SFs size 128 unit entry dpipe_tables none
  pci/0000:03:00.1/196708:
    name max_SFs size 128 unit entry dpipe_tables none
  pci/0000:03:00.1/196709:
    name max_SFs size 128 unit entry dpipe_tables none
