Subject: [037/289] ath9k_hw: Set proper eeprom offset for AR9287 HTC devices

2.6.36-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Rajkumar Manoharan <rmanoharan@...eros.com>

commit b5261cf4f3860bd772346a3e692683b6144dd44c upstream.

AR9287 based PCI & USB devices are differed in eeprom start offset.
So set proper the offset for HTC devices to read nvram correctly.
