This patch exposes OMAP4 thermal sensor as a thermal zone
named "cpu". Only thermal creation is done here.

TODO:

 - Add cooling bindings
 - Add extrapolation rules

It's more of IP feature than OMAP specific, so something like

config  HAVE_BANDGAP_THERMAL_SUPPORT

and then let processor's which support enable it. That OMAP varients
in AMXX etc if needed can make use of it.
Those are just an OMAP in disguise.
If you agree, then rest of the driver also can be cleaned to avoid
omap_* in file names and variables.

Apart from this minor comment, rest of the patch looks fine to me.
Then it will appear as a fully generic bandgap driver, which is not the
case. This is really a TI thing, right ?
