This adds a Nokia N900 quirk, so that the V28
regulator is used for the omapdss.sdi port.
This quirk is needed until omapdss is converted
to DT, so that the regulator can be acquired via
a phandle.
On other boards the regulator can be renamed in
the DT data, but on the Nokia N900 the regulator
is also used for other hardware components.
