[PATCH] cxl/region: use %pap format to print resource_size_t

[Randy Dunlap]

Use "%pap" to print a resource_size_t (phys_addr_t derived type)
to prevent build warnings on 32-bit arches (seen on i386 and
riscv-32).

../drivers/cxl/core/region.c: In function 'alloc_hpa':
../drivers/cxl/core/region.c:556:25: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 5 has type 'resource_size_t' {aka 'unsigned int'} [-Wformat=]
  556 |                         "HPA allocation error (%ld) for size:%#llx in %s %pr\n",

Fixes: 7984d22f1315 ("cxl/region: Add dev_dbg() detail on failure to allocate HPA space")

Applied, thanks Randy.
