Simple update on documentation file for DT. This patch
also adds an example for OMAP4430 and 0MAP4470, and also updated
OMAP4460's example.

the talert signal is routed to;
Specific:
- ti,tshut-gpio : this entry should be used to inform which GPIO
line the tshut signal is routed to;
+- regs : this entry must also be specified and it is specific
+to each bandgap version, because the mapping may change from
+soc to soc, apart of depending on available features.
