We get a warning about the missing MODULE_LICENSE tag for this newly
added driver module:
WARNING: modpost: missing MODULE_LICENSE() in drivers/dma/xilinx/zynqmp_dma.o
see include/linux/module.h for more information
This adds a "GPL" license, matching the "version 2 or later" information in
the comment at the start of the file.

The newly added zynqmp_dma driver produces a warning on 32-bit architectures
when dma_addr_t is 64-bit wide:
drivers/dma/xilinx/zynqmp_dma.c: In function 'zynqmp_dma_config_sg_ll_desc':
drivers/dma/xilinx/zynqmp_dma.c:321:9: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
((dma_addr_t)sdesc - (dma_addr_t)chan->desc_pool_v);
^
drivers/dma/xilinx/zynqmp_dma.c:321:29: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
((dma_addr_t)sdesc - (dma_addr_t)chan->desc_pool_v);
This changes the cast to the more appropriate uintptr_t.

UltraScale+ MPSoC. This dma controller supports memory to memory
and I/O to I/O buffer transfers.
