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

[Sasha Levin]

Commit fbb22ceaaf8f ("powerpc/irq: Make irqstats array based") made
arch_show_interrupts() call irq_proc_emit_counts(). That function lives
in kernel/irq/proc.c, which is only built with CONFIG_PROC_FS, so
kernels without procfs no longer link:

  powerpc64-linux-ld: arch/powerpc/kernel/irq.o: in function `arch_show_interrupts':
  arch/powerpc/kernel/irq.c:134:(.text+0x4b8c): undefined reference to `irq_proc_emit_counts'

arch_show_interrupts() is only called from irq_seq_show(), which is in
kernel/irq/proc.c as well, so build it only with CONFIG_PROC_FS, as x86
already does.

Fixes: fbb22ceaaf8f ("powerpc/irq: Make irqstats array based")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202609271531.8kf2NTjK-lkp@intel.com/

fbb22ceaaf8f came in with bb2235894a8a ("Merge tag 'powerpc-7.4-1' of
git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux"), so
mainline is affected now. Build-tested with the ppc64 randconfig from the
report, a ppc32 tinyconfig with LD_DEAD_CODE_DATA_ELIMINATION disabled
(it hides the error otherwise) and ppc64_defconfig.

Diff is same. Since it made into linus tree already, all is well.
