drm/msm: fix address space warning

Browse Source 
In the linux-4.19 stable kernel, we get a warning about a type
mismatch between phys_addr_t and dma_addr_t:

drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.c: In function '_dpu_dbg_dump_dpu_dbg_bus':
drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.c:2003:16: error: passing argument 3 of 'dma_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]

This code was removed in linux-4.20 with upstream commit effec874792f
("drm/msm/dpu: Remove dpu_dbg"). Rather than backporting the large
patch, this just fixes the warning by using the correct type.
