commit 90d4d3f4ea upstream.
Even though commit cfb5d65f25 ("ARM: dts: dra7: Add bus_dma_limit
for L3 bus") added bus_dma_limit for L3 bus, the PCIe controller
gets incorrect value of bus_dma_limit.
Fix it by adding empty dma-ranges property to axi@0 and axi@1
(parent device tree node of PCIe controller).
