Hangbin Liu 8d0c314c30 tools: ynl-gen: support using pre-defined values in attr checks
Support using pre-defined values in checks so we don't need to use hard
code number for the string, binary length. e.g. we have a definition like

 #define TEAM_STRING_MAX_LEN 32

Which defined in yaml like:

 definitions:
   -
     name: string-max-len
     type: const
     value: 32

It can be used in the attribute-sets like

attribute-sets:
  -
    name: attr-option
    name-prefix: team-attr-option-
    attributes:
      -
        name: name
        type: string
        checks:
          len: string-max-len

With this patch it will be converted to

[TEAM_ATTR_OPTION_NAME] = { .type = NLA_STRING, .len = TEAM_STRING_MAX_LEN, }
