Steps to Reproduce

Include the following statements (taken from NXOS) into Yang model and then build go bundle:

typedef comp_InstType {
    type enumeration {
        enum unknown {
            value 0;   // Unknown
        }
        enum phys {
            value 1;     // Baremetal Host
        }
        enum virt {
            value 2;     // Virtual Machine
        }
        enum hv {
            value 3;   // Hypervisor Host
        }
    }
    default "unknown";
}

typedef comp_NicInstType {
    type comp_InstType;
}

In this model the "comp_NicInstType" type "cascades" or "repeats" definition of "comp_InstType"

The Go API builder creates duplicate statements like this one, which causes compiler syntax error

// CompInstType
type CompInstType int
const (
CompInstType_unknown CompInstType = 0
CompInstType_phys CompInstType = 1
CompInstType_virt CompInstType = 2
CompInstType_hv CompInstType = 3
)

The type CompNicInstType does not appear in the Go code.

Additional notes

The issue does not appear in C++ and Python bundle builders.
