lib/genalloc: add a helper function for DMA buffer allocation
When using pool space for DMA buffer, there might be duplicated calling of
gen_pool_alloc() and gen_pool_virt_to_phys() in each implementation.
Thus it's better to add a simple helper function, a compatible one to the
common dma_alloc_coherent(), to save some code.
