  SVN rev 221667 on 2011-05-08 15:55:52Z by adrian
  
  Fix the 5ghz fast clock logic.
  
  The macro which I incorrectly copied into ah_internal.h assumed
  that it'd be called with an AR_SREV_MERLIN_20() check to ensure
  it was only enabled for Merlin (AR9280) silicon revision 2.0 or
  later.
  
  Trouble is, the 5GHz fast clock EEPROM flag is only valid for
  EEPROM revision 16 or greater; it's assumed to be enabled
  by default for Merlin rev >= 2.0. This meant it'd be incorrectly
  set for AR5416 and AR9160 in 5GHz mode.
  
  This would have affected non-default clock timings such as SIFS,
  ACK and slot time. The incorrect slot time was very likely wrong
  for 5ghz mode.
