Subject: [PATCH] dmaengine: ti: edma: Remove some unused functions

These functions are defined in the edma.c file, but not called elsewhere,
so delete these unused functions.

drivers/dma/ti/edma.c:746:31: warning: unused function 'to_edma_cc'.
drivers/dma/ti/edma.c:420:20: warning: unused function 'edma_param_or'.
drivers/dma/ti/edma.c:414:20: warning: unused function 'edma_param_and'.
drivers/dma/ti/edma.c:402:20: warning: unused function 'edma_param_write'.
drivers/dma/ti/edma.c:373:28: warning: unused function 'edma_shadow0_read'.
drivers/dma/ti/edma.c:396:28: warning: unused function 'edma_param_read'.
drivers/dma/ti/edma.c:355:20: warning: unused function 'edma_or_array'.
