tegra: hwpm: remove support-soc-tools dependency

Browse Source 
Property support-soc-tools was added mainly to provide user's control to
enable/disable HWPM feature. Since, the same functionality can be
achieved using "status" in device node, support-soc-tools property is
redundant. Hence, this property is removed from HWPM device node.
Update HWPM driver probe to not depend on support-soc-tools property.
