devlink: Add resource scope filtering to resource dump

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
