[PATCH] powerpc/eeh: Fix build failure with CONFIG_PROC_FS=n

[Michael Ellerman]

The build fails with CONFIG_PROC_FS=n:

  arch/powerpc/kernel/eeh.c:1571:12: error: ‘proc_eeh_show’ defined but not used
   1571 | static int proc_eeh_show(struct seq_file *m, void *v)

Wrap proc_eeh_show() in an ifdef to avoid it.
