powerpc/mpc512x: fix resource printk format warning

[ Upstream commit 7538c97e2b80ff6b7a8ea2ecf16a04355461b439 ]

Use "%pa" format specifier for resource_size_t to avoid a compiler
printk format warning.

../arch/powerpc/platforms/512x/clock-commonclk.c: In function 'mpc5121_clk_provide_backwards_compat':
../arch/powerpc/platforms/512x/clock-commonclk.c:989:44: error: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' {aka 'long long unsigned int'} [-Werror=format=]
  989 |         snprintf(devname, sizeof(devname), "%08x.%s", res.start, np->name); \
      |                                            ^~~~~~~~~  ~~~~~~~~~
      |                                                          |

Prevents 24 such warnings.
