Subject: [PATCH 1/5] dmaengine: dw-edma: Drop unused dchan2dev() and
 chan2dev()

Static functions dchan2dev() and chan2dev() are not used, W=1 build:

  dw-edma-core.c:27:16: error: unused function 'dchan2dev' [-Werror,-Wunused-function]
  dw-edma-core.c:33:16: error: unused function 'chan2dev' [-Werror,-Wunused-function]

Fixes: e63d79d1ffcd ("dmaengine: Add Synopsys eDMA IP core driver")
