We get below errors when we try to enable debug logs in book3s64/hash_utils.c
This patch fixes these errors related to phys_addr_t printf format.

arch/powerpc/mm/book3s64/hash_utils.c: In function ‘htab_initialize’:
arch/powerpc/mm/book3s64/hash_utils.c:1401:21: error: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 2 has type ‘phys_addr_t’ {aka ‘long long unsigned int’} [-Werror=format=]
 1401 |                 DBG("creating mapping for region: %lx..%lx (prot: %lx)\n",
