cxl: Fix emit of type resource_size_t argument for validate_region_offset() 



0day reported warnings of:
drivers/cxl/core/region.c:3664:25: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 4 has type 'resource_size_t' {aka 'unsigned int'} [-Wformat=]

drivers/cxl/core/region.c:3671:37: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 4 has type 'resource_size_t' {aka 'unsigned int'} [-Wformat=]

Replace %#llx with %pr to emit resource_size_t arguments.
