iwlwifi: correct API command overlap

Correct the API commands where same command id used for two different
commands. Update max api versions for affected devices.

TX_ANT_CONFIGURATION_CMD was already using id 0x98, so
REPLY_TX_POWER_DBM_CMD moved to 0x95

Older API interfaces may used original value so V1 defines provided.
