Subject: [PATCH 14/14] thermal: ti-soc-thermal: remove SoC family config
 options

   1292     224       0    1516     5ec drivers/thermal/ti-soc-thermal/omap4-thermal-data.o

Maximum possible space savings (CONFIG_OMAP3_THERMAL=y with
other config options set to n) are down from ~7kB to ~3kB so
it is not really worth to have extra complexity and keep SoC
family config options. Just remove them.
