The sg_dma_len() returns unsigned int but we had driver print it as %zu, use
%u as documented in Documentation/printk-formats.txt
drivers/dma/sun6i-dma.c: In function ‘sun6i_dma_prep_slave_sg’:
drivers/dma/sun6i-dma.c:643: warning: format ‘%zu’ expects type ‘size_t’,
but argument 8 has type ‘unsigned int’

Since the driver defined COMPILE_TEST, it gets compiled for different arch's
The driver uses __virt_to_phys() insteadof virt_to_phys, so replace it

The Allwinner A31 has a 16 channels DMA controller that it shares with the
newer A23. Although sharing some similarities with the DMA controller of the
older Allwinner SoCs, it's significantly different, I don't expect it to be
possible to share the driver for these two.
The A31 Controller is able to memory-to-memory or memory-to-device transfers on
the 16 channels in parallel.
