ath6kl: fix firmware start address for ar6003 hw2.0

Sangwook found out that commit 639d0b89 ("ath6kl: read firmware start
address from hardware") broke firmware boot on ar6003 hw2.0 as it seems
it's not posible to automatically query the address from hardware. So
we need to hardcode the address for hw2.0.

ath6kl: Indicate the roaming capability of the firmware

When the rssi of the current AP drops, both wpa_supplicant and the
firmware may do a background scan to find a better AP and try to
associate. This might lead to a race condition where both may try
to connect to some AP based on their scan results.

Since the firmware is capable of handling roaming, let
wpa_supplicant know about this capability so that it will back off
from bgscan based roaming.

Currently the load address was calculated everytime when it was needed,

Also move the code just after target version is retrieved. That way it's
