Parameters

  InstancePtr | is a pointer to the XDpRxSs core instance.
  CfgPtr | points to the configuration structure associated with the DisplayPort RX Subsystem core.
  EffectiveAddr | is the base address of the device. If address translation is being used, then this parameter must reflect the virtual base address. Otherwise, the physical address should be used.

Returns
  - XST_DEVICE_NOT_FOUND if sub-core not found.
  - XST_FAILURE if sub-core initialization failed.
  - XST_SUCCESS if XDpRxSs_CfgInitialize successful.

Note
  None.
