mmc: mmci: create common mmci_dma_setup/release
This patch creates a common mmci_dma_setup/release which calls
dma_setup/release callbacks of mmci_host_ops and manages
common features like use_dma... If there is a fallbacks to
pio mode, dma functions must check use_dma.
error management:
-mmci_dmae_setup fail if Tx and Rx dma channels are not defined
-qcom_dma_setup fail if one of both dma channels is not defined,
Qcom has no specific resource to release, just mmci dmae resource.
