Adrian Chadd 76355edba5 Teach if_ath about devices which have short-GI in 20MHz channel modes.
This has been disabled until now because there hasn't been any supported
device which has this feature. Since the AR9287 is the first device to
support it, and since now the HAL has functional AR9287+11n support,
flip this on.
