Subject: [PATCH] dmaengine: ste_dma40: use proper format string for resource_size_t

From: Arnd Bergmann <arnd@...db.de>

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")
