thermal: add support for thermal sensor present on SPEAr13xx machines

Browse source 
ST's SPEAr13xx machines are based on CortexA9 ARM processors.  These
machines contain a thermal sensor for junction temperature monitoring.

This patch adds support for this thermal sensor in existing thermal
framework.
