[net-next RFC PATCH 4/4] net: dsa: qca8k: split qca8k in common and 8xxx specific code

Christian Marangi
2022-07-16T17:50:54Z

The qca8k family reg structure is also used in the internal ipq40xx
switch. Split qca8k common code from specific code for future
implementation of ipq40xx internal switch based on qca8k.

While at it also fix minor wrong format for comments and reallign
function as we had to drop static declaration.
