[patch 36/38] CKRM e18: Classification Engine Configuration Support cleanup

[Gerrit Huizenga <gh@us.ibm.com>]

Make the configuration interface more accurately reflect the relationship between RBCE and CRBCE. Only the following 4 configurations are allowed:

  | CONFIG_RBCE | CONFIG_CRBCE |
--+-------------+--------------|
1 |      m      |       m      |
2 |      y      |       n      |
3 |      n      |       y      |
4 |      n      |       n      |
