dmaengine: Remove device_prep_dma_imm_data from struct dma_device

Commit Message

From: Nathan Lynch <[e-mail]>

The device_prep_dma_imm_data() method isn't implemented or invoked by
any code since commit 80ade22c06ca ("misc: mic: remove the MIC drivers").

Remove it, shrinking struct dma_device by a few bytes.
