Bob Copeland f650470a8f ath5k: enable combined michael mic in key cache 
For mac revisions >= "Griffin," the hardware allows the mic tx and rx
authenticator keys to share the same cache line, whereas earlier
hardware can only store the rx.  Enable the combined mic on hardware
that supports it.

* 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.

* check the eeprom status register
* and read eeprom data register.

* 5211 - write offset to AR5K_EEPROM_BASE
* 5212 write AR5K_EEPROM_CMD_READ on AR5K_EEPROM_CMD
* check the eeprom status register
* and read eeprom data register.

* To write eeprom data for a specific offset:
* 5210 - enable eeprom access (AR5K_PCICFG_EEAE)

/*
* RF Buffer register
*
* There are some special control registers on the RF chip
* that hold various operation settings related mostly to
* the analog parts (channel, gain adjustment etc).
*
* We don't write on those registers directly but
* we send a data packet on the buffer register and
* then write on another special register to notify hw
* to apply the settings. This is done so that control registers
* can be dynamicaly programmed during operation and the settings
* are applied faster on the hw.
*
* We sent such data packets during rf initialization and channel change
* through ath5k_hw_rf*_rfregs and ath5k_hw_rf*_channel functions.
*
* The data packets we send during initializadion are inside ath5k_ini_rf
* struct (see ath5k_hw.h) and each one is related to an "rf register bank".
* We use *rfregs functions to modify them acording to current operation
* mode and eeprom values and pass them all together to the chip.
*
* It's obvious from the code that 0x989c is the buffer register but
* for the other special registers that we write to after sending each
* packet, i have no idea. So i'll name them BUFFER_CONTROL_X registers
* for now. It's interesting that they are also used for some other operations.
*
* Also check out hw.h and U.S. Patent 6677779 B1 (about buffer
* registers and control registers):
