When doing randconfig builds for sparc32 with COMPILE_TEST,
some (non-Sparc) drivers cause kconfig warnings with the
Kconfig symbols PM, PM_GENERIC_DOMAINS, or PM_GENERIC_DOMAINS_OF.

This is due to arch/sparc/Kconfig not using the PM Kconfig for
Sparc32:

  if SPARC64
  source "kernel/power/Kconfig"
  endif

Arnd suggested adding "|| COMPILE_TEST" to the conditional,
instead of trying to track down every driver that selects
any of these PM symbols.

Fixes the following kconfig warnings:

I hope Andrew picks this up.
