Jouni Malinen 4848a38d85 Get rid of duplicated cipher suite and AKM definitions 
WPA_CIPHER_* and CIPHER_* are used for the exact same set of cipher
suites with the main difference being that the WPA_CIPHER_* version is
suitable to be used as a bitfield. Similarly, WPA_KEY_MGMT_* and
KEY_MGMT_* have similar design for AKMs. There is no need to maintain
two separate copies of the definitions since the bitfield compatible
version can be used for both needs. Get rid of the CIPHER_* and
KEY_MGMT_* versions to clean up the implementation by getting rid of
unnecessary mapping functions.
