Subject: Remove AR6002_REV43 flag in Makefile
This flag is for AR6003 hw 2.1.1 firmware only.
Confirm with RF/FW engineer, Driver set this flag will cause
driver to read wrong data by an extra shift.
ar6003_remove_AR6002_REV43.patch is based on an accepted patch -
kernel-adaptation-mrst-2.6.37.6-92.2 and ar6003_cfg_syncup_v2.patch.
