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.

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.
