dma-mapping: move all DMA mapping code to kernel/dma Currently the code is split over various files with dma- prefixes in the lib/ and drives/base directories, and the number of files keeps growing. Move them into a single directory to keep the code together and remove the file name prefixes. To match the irq infrastructure this directory is placed under the kernel/ directory.

dma-mapping: add the missing ARCH_HAS_SYNC_DMA_FOR_CPU_ALL declaration The patch adding the infrastructure failed to actually add the symbol declaration, oops..
