When LPAE is set, both the dma_addr_t and resource_size_t become 64 bit
wide, causing a warning about the format string:
drivers/dma/ste_dma40.c: In function 'd40_probe':
drivers/dma/ste_dma40.c:3539:23: error: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' {aka 'long long unsigned int'} [-Werror=format=]
3539 | dev_info(dev, "found LCPA SRAM at 0x%08x, size 0x%08x\n",
Change both to the special %pap and %pap helpers for these types.
Fixes: 5a1a3b9c19dd ("dmaengine: ste_dma40: Get LCPA SRAM from SRAM node")

I think yours is wrong: you use %pR with a resource_size_t, but it
expects a "struct resource instead".
