Building sandbox_defconfig on ARMv7 with HOST_32BIT=y results in:
drivers/misc/qfw_sandbox.c:51:25: warning:
cast to pointer from integer of different size [-Wint-to-pointer-cast]
51 | void *address = (void *)be64_to_cpu(dma->address);
Add the missing type conversion.
Fixes: 69512551aa ("test: qemu: add qfw sandbox driver, dm tests, qemu tests")
