[PATCH] pmdomain: renesas: rcar-sysc: Update description of chan_offs

[Ayman Chaudhry]

The description of `rcar_sysc_area.chan_offs` does not clearly document
how the field is used.

When `rcar_sysc_area.flags` is set to `PD_ALWAYS_ON`,
`rcar_sysc_area.chan_offs` gets ignored, therefore improve the
description of `rcar_sysc_area.chan_offs` to make it clear that the
field is set to 0 if power is always on.
