staging: omap-thermal: add OMAP4 data structures

This patch adds the data structures needed for proper registration
of OMAP4 chips. This patch includes definitions for these chip versions:
. OMAP4430
. OMAP4460
. OMAP4470

If you say yes here you get thermal support for the Texas Instruments
OMAP4 SoC family. The current chip supported are:
- OMAP4430
- OMAP4460
- OMAP4470
This includes alert interrupts generation and also the TSHUT
support.
