IO resources, x86: ioremap sanity check to catch mapping requests exceeding, fix

fix this build error:

 kernel/resource.c: In function 'iomem_map_sanity_check':
 kernel/resource.c:842: error: implicit declaration of function 'r_next'
 kernel/resource.c:842: warning: assignment makes pointer from integer without a cast

r_next() was only available if CONFIG_PROCFS was enabled.

and fix this build warning:

 kernel/resource.c:855: warning: format '%llx' expects type 'long long unsigned int', but argument 2 has type 'resource_size_t'
 kernel/resource.c:855: warning: format '%llx' expects type 'long long unsigned int', but argument 3 has type 'long unsigned int'
 kernel/resource.c:855: warning: format '%llx' expects type 'long long unsigned int', but argument 4 has type 'resource_size_t'
 kernel/resource.c:855: warning: format '%llx' expects type 'long long unsigned int', but argument 5 has type 'resource_size_t'

resource_t can be 32 bits.
