When extending the capability detection logic for 4xxx devices the SMx algorithms were accidentally missed. Enable these SMx capabilities by default for QAT GEN4 devices. Check for device variants where the SMx algorithms are explicitly disabled by the GEN4 hardware. This is indicated in fusectl1 register. Mask out SM3 and SM4 based on a bit specific to those algorithms. Mask out SM2 if the PKE slice is not present.
