rS345288: Prevent loading SGX with incorrect EPC data

Summary

On my machine even if sgx is disabled in firmware the driver still tries to attach with EPS base and size equal to zeroes.
Such behavior results in kernel panic when the module is unloaded.
This is probably caused by a crappy firmware.
Add a simple check to make sure that those values are not zeroes.
