[PATCH v3] asha: allow LE 2M PHY on the audio channel

[PATCH v3] asha: allow LE 2M PHY on the audio channel

[Kyle Pepper]

Allow LE 2M alongside LE 1M on the connected audio socket before starting
ASHA. Keep streaming if the kernel cannot set the PHY preference.

Changes since v2:
- Drop the standalone PHY unit test and its build/ignore entries.
- Reuse the existing test/simple-asha playback script.

Validation: builds without warnings, 35/35 native unit binaries,
and checkpatch pass.
