drm/amdgpu: use %pap format string for phys_addr_t

The newly added get_local_mem_info() function prints a phys_addr_t
using 0x%llx, which is wrong on most 32-bit systems, as shown by
this warning:

drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.c: In function 'get_local_mem_info':
include/linux/kern_levels.h:5:18: error: format '%llx' expects argument of type 'long long unsigned int', but argument 2 has type 'resource_size_t {aka unsigned int}' [-Werror=format=]
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.c:297:31: note: format string is defined here
pr_debug("Address base: 0x%llx limit 0x%llx public 0x%llx private 0x%llx\n",

Passing the address by reference to the special %pap format string will
produce the correct output and avoid the warning.
