stdlib: Add support for DSU dependent devices

Add support for devices that depend on DSU for power estimates. The
callflow will short circuit device-specific tables that are unnecessary
for that device's calculation. For example, a device that depends on DSU
calculations will short circuit tables that use CPU dependent
calculations.

Runtime of existing Wattson test cases remain the same before and after
this patch (~4300ms).
