[PATCH v2 9/9] pinctrl: single: dump pinmux register value

This makes sense, but should be done using pcs_read, not pcs_readl,
see below.

> Also fix the issue on caluclating pin offset. The last parameter

You should not use pcs_readl here directly as the register
width can vary. Can you please update the patch for that and
make it independent from the rest of the series? That way we
can merge the fix for v3.7-rc series.
