I just noticed that the recently merhed Poplar board has these GPIO
lines named "LS-GPIO-A" etc.

We have to decide for one format. Either "LS-GPIO-A" or just "GPIO-A"
and change all the others (including this patch).

The namespace needs to be consistent across all 96boards.

Wei et al: what do you prefer? I can fix it up either way.

If we want it "LS-GPIO-A" then we need to patch up the old 6220
DTS as well.

Yours,
