[ Upstream commit 27f13774654ea6bd0b6fc9b97cce8d19e5735661 ] 'dma-ranges' in a PCI bridge node does correctly set dma masks for PCI devices not described in the DT. Certain DRA7 platforms (e.g., DRA76) has RAM above 32-bit boundary (accessible with LPAE config) though the PCIe bridge will be able to access only 32-bits. Add 'dma-ranges' property in PCIe RC DT nodes to indicate the host bridge can access only 32 bits.
