This patch improves the code that handles threshold values
by creating single functions that are usable for tcold and
thot. This way we won't have duplicated functionality just
because it is handling different bitfields. Now
the added functions are reused in several places where
it is needed to update any threshold.

This patch also removes macros that are used only inside
the _validate helper function.

In this patch there is also an addition of an extra function
section for Exposed APIs, used outside the omap-bandgap.c,
but inside the omap-thermal driver.
