It looks like you accidentally copied the ranges from keystone, even though that has a 64-bit root bus and you only have 32-bit.
I suspect what you want is
dma-ranges = <0x80000000 0 0x80000000>;
to translate dma_addr_t 0x80000000-0xffffffff to phys_addr_t 0x0-0x7fffffff rather than phys_addr_t 0x800000000-0x87fffffff.
