imx8ulp: soc: Check the DBD_EN fuse before setting RDC

S400 enables RDC only when the DBD_EN is fused. Otherwise, the RDC
is allowed by all masters.

Current S400 has issue if the XRDC has released to A35, then A35 reset
will fail in ROM due to S400 fails to get XRDC.
So temp work around is checking the DBD_EN, if it is not fused, we
don't need to call release XRDC or TRDC.
