perf/arm-cmn: Fix resource_size_t printk specifier in arm_cmn_init_dtc()

When building for 32-bit ARM, there is a warning when using the %llx
specifier to print a resource_size_t variable:

  drivers/perf/arm-cmn.c: In function 'arm_cmn_init_dtc':
  drivers/perf/arm-cmn.c:2149:73: error: format '%llx' expects argument of type 'long long unsigned int', but argument 4 has type 'resource_size_t' {aka 'unsigned int'} [-Werror=format=]
   2149 |                                      "Failed to request DTC region 0x%llx\n", base);
        |                                                                      ~~~^     ~~~~
        |                                                                         |     |
        |                                                                         |     resource_size_t {aka unsigned int}
        |                                                                         long long unsigned int
        |                                                                      %x

Use the %pa specifier to handle the possible sizes of phys_addr_t
properly. This requires passing the variable by reference.
