Subject: [PATCH 04/17] spi: dw: Cleanup generic DW DMA code namings
Since from now the former Intel MID platform layer will be used
as a generic DW SPI DMA module, lets alter the internal methods
naming to be DMA-related instead of having the "mid_" prefix. In
addition the DW PCI-DMA specific methods and structures should
be named with pci-suffexes, since we'll implement the DW MMIO DMA
specific functions and objects soon.
