ad9081/_mc: fix type and first channel defaulting

[gastmaier]

Description

Some attributes are fetched from the first channel, and if multichip, from the first device:

• ad9081: [...]
• ad9081_mc: {'dev1': [...], 'dev2': [...],}

Due to the type change, examples/QuadMxFE_dual_example.py was broken.
Use the method overwrite to fix the type and behavior.

Hi, I run again with the exact black version

the differences from the updated #660 to the current version (broken for newer python) are pretty much the force push diff https://github.com/analogdevicesinc/pyadi-iio/compare/7e64edd25d2e38956f9d6ad254510402c2deebf7..c829354697aa6ff7507775a3850efe02ee7ffd89
