Don't allow user to enable QAT chart

This commit adds the code to raise the error for the following command,
if the hardware does not have 4940 or 4942 QAT devices.
Command: "helm-chart-attribute-modify  --enabled true
intel-device-plugins-operator intel-device-plugins-qat
intel-device-plugins-operator"

TEST CASES:

PASSED: Build is success.
PASSED: Bootstrap is success.
PASSED: Upload the package using command system application-upload.
PASSED: Check chart enabled status using command
        "system helm-override-list intel-device-plugins-operator --long"
PASSED: Enable the QAT chart using command "system
        helm-chart-attribute-modify", raises error in non QAT system.
PASSED: Enable the QAT chart using command "system
        helm-chart-attribute-modify", it should success on QAT system.
PASSED: Disable the QAT chart using command "system
        helm-chart-attribute-modify", it should success in both QAT and
        non QAT system.
PASSED: Apply app intel-device-plugins-operator on both QAT and non QAT
        system is successful.
