common: dma-mapping: introduce generic alloc() and free() methods
Introduce new generic alloc and free methods with attributes argument.
Existing alloc_coherent and free_coherent can be implemented on top of the
new calls with NULL attributes argument. Later also dma_alloc_non_coherent
can be implemented using DMA_ATTR_NONCOHERENT attribute as well as
dma_alloc_writecombine with separate DMA_ATTR_WRITECOMBINE attribute.
This way the drivers will get more generic, platform independent way of
allocating dma buffers with specific parameters.
