cxl: Fix warning from emitting resource_size_t as long long int on 32bit systems

Reported by kernel test bot from an ARM build:
drivers/cxl/core/region.c:3263:26: warning: format '%lld' expects argument of type 'long long int', but argument 3 has type 'resource_size_t' {aka 'unsigned int'} [-Wformat=]

On a 32bit system, resource_size_t is defined as 32bit long vs on a 64bit
system it is defined as 64bit long. Use %pa format to deal with
resource_size_t.
