This patch fixes a embarrassing bug which was introduced by:
"[PATCH] ar9170: implement frequency calibration for one-stage/openfw"

The phy_data variable initialization has to done outside the for-loop
scope. This is because the for-loop uses u32 phy_data variable more
like a 4-byte field. But in each run only a single byte is calculated.
Therefore phy_data content needs to stay the same for at least 3 more
iterations, before the complete set can be uploaded.

apply the conformance test limits (CTL) stored in the eeprom upon
the values calculated for the tx power (ar->power_*).

This is based on the implementation in the vendor driver
(hal/hpmain.c, line 3700 ff.) with one difference:
If any ctl mode isn't found in the eeprom, we fall back to the "lower",
legacy modes (5GHT20,11A or 2GHT20,11G,11B). Otus only did 5GHT20->11A.

Currently CTL are applied for the FCC group only.

This patch ports some code from the vendor driver, which is
supposed to upload the right calibration values for the
chosen frequency.

In theory, this should give a better range and throughput
for all users with the open, or one-stage firmware.
