mediatek: remove condition in Device/Default

The current condition with part of the variables set dependent on
the subtarget in Device/Default isn't really nice to read and also
defeats the purpose of having a default node.

This removes the special settings for mt7623 and moves them to the
individual devices, which is not much of a problem as there are
actually just two of them and they partly use different settings
anyway.

While at it, slightly adjust the order of variables and wrap some
long lines.
