Introduce new generic alloc and free methods with attributes argument.

    The method names don't match the ones in the subject.

Right, I will reword the subject to "common: dma-mapping: introduce generic alloc()
and free() methods".

quoted

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.
