ar71xx: backport fixes for better CPE210/510 support
This patchset enables the RX LNA for the CPE210/510, improving RX by about
20dB. The profiles for CPE210 and CPE510 is split into two images, so the
CPE510 can use the correct ART offset, improving the TX power by 10dB.

Fixes #796

Subject: ar71xx/cpe510: enable LNA for CPE210/220/510/520
The LNA improves the rx path. Within a simple test setup
it improved the signal from -60dbm to -40dbm.
