MLK-20583-2 imx: mx6sabreauto: Enable OCOTP CTRL clock in DCD and plugin

The HAB code can not set Field Return and SRK Revoke sticky bits in case
OCOTP CTRL clock is gated out.

In case we disable OCOTP CTRL clock in DCD and plugin those features may
not operate as expected.

Keep OCOTP CTRL clock enabled in DCD and plugin so HAB can propely lock
those features, users should use the CSF Unlock command to prevent those
features from being locked.
