    dmaengine: dw-edma: Add HDMA remote interrupt configuration
    
    [ Upstream commit e2f6a5789051ee9c632f27a12d0f01f0cbf78aac ]
    
    Only the local interruption was configured, remote interrupt was left
    behind. This patch fix it by setting stop and abort remote interrupts when
    the DW_EDMA_CHIP_LOCAL flag is not set.
