Checkpoint regulatory gutting:
o move toward eliminating HAL_CHANNEL; for now it's still present but
  rework api's so a switch to an 802.11 channel is more possible
o move toward stripping duplicate info from HAL_CHANNEL_INTERNAL; this
  is now referenced using ic_devdata in the 802.11 channel and real soon
  all callers will have the 802.11 channel to find the frequency and
  channel attributes (the only issue remaining is ath_hal_process_noisefloor)
o eliminate code to write the HAL_CHANNEL on channel change; this was
  done to update the tx power for AR/DFS after a reset (so tx power
  scaling and CTL enforcement was applied) but was wrong and needs to
  be handled differently
o change getChipPowerLimits api to work on a single channel
o change ath_hal_getctl api to work on an internal channel
o overhaul regulatory code:
  - remove per-country regulatory constraint work: having the hal construct
    this state duplicates what's already done in layers above; instead we'll
    push any initial sku/country code up as a hint that can be acted on to
    form regulatory state that is plumbed
  - switch to net80211 country code definitions
  - strip 900Mhz stuff; we can now handle this entirely in the driver
  - remove channel sorting; instead tag 802.11 channels with the index of
    the internal channel table (for now we check the frequency and flags
    to insure a match but eventually we'll ditch that and also compress
    all entries for a frequency into one)
  - remove various enforcements that are now meaningless; all we want to do
    is construct an initial regulatory hint/channel list from the EEPROM and
    thereafter trust channel lists that come down from above
  - move CTL to HAL_CHANNEL_INTERNAL for now; it'll be constructed on the
    fly once we merge channel entries for the same frequency
  - change ath_hal_init_channels api to operate directly on 802.11 channels;
    this call is used to check the EEPROM and construct an initial channel
    list (but the api also permits explicit override, use CTRY_DEFAULT/SKU_NONE
    to use the EEPROM contents)
  - add ath_hal_getchannels api to retrieve a channel list according to
    builtin rules but without altering any runtime state (unlike
    ath_hal_init_channels); this is used, in particular, to retrieve the
    device capabilities needed by the getradiocaps driver callback
  - add ath_hal_set_channels api to take 802.11 regulatory state and setup
    required internal state such as CTL's; this is used to implement the
    setregdomain driver callback
  - remove ah_countryCode from the internal state; it's no longer needed
  - move CHANNEL_NFCREQUIRED from privFlags to channelFlags (for now); it
    will eventually use one of the driver-private bits in ic_flags
  - change ar5212GetChipPowerLimits to not apply power scaling and CTL's
    to the values returned for min/max tx power; using ar5212SetRateTable
    to do this was bad as it clobbers runtime state (need to revisit)
  - add new status codes to disambiguate errors in regulatory calls
  - move CHANNEL_DFS to match net80211 definition
  - move CHANNEL_4MS_LIMIT to match net80211 definition
  - remove CTRY_DEBUG and CTRY_DEFAULT in favor of net80211 defs
  - remove ath_hal_isgsmsku; the hal no longer knows about GSM
