DRC issue related to unused port of ACORE

[sjkim85]

In adbg_intf there still exist unused in/out ports for replica ADCs The unused output ports (pfd_inp_meas/pfd_inn_meas ) cause floating gate errors in DRC. These port should be eliminated from adbg_intf or replica ADC needs to be updated for next tape-out sel_pfd_in sel_pfd_in_meas en_pfd_inp_meas en_pfd_inn_meas pfd_inp_meas pfd_inn_meas
