Bruno Randolf 0edc9a6709 ath5k: Use high bitrates for ACK/CTS 
There was a confusion in the usage of the bits AR5K_STA_ID1_ACKCTS_6MB and
AR5K_STA_ID1_BASE_RATE_11B. If they are set (1), we will get lower bitrates for
ACK and CTS. Therefore ath5k_hw_set_ack_bitrate_high(ah, false) actually
resulted in high bitrates, which i think is what we want anyways. Cleared the
confusion and added some documentation.

* So SNAPPEDBCRVALID sould also stand for "snapped BCR -values- valid", so i
* renamed it to SNAPSHOTSVALID to make more sense. I realy have no idea what
* else can it be. I also renamed SNPBCMD to SNPADHOC to match BCR.

* 5211 - write offset to AR5K_EEPROM_BASE
* 5212 write AR5K_EEPROM_CMD_READ on AR5K_EEPROM_CMD
