[PATCH] ARM: zx: only build power domain code when CONFIG_PM=y

The newly added zx power domain code causes build errors in
some configurations:

warning: (PM_RMOBILE && SOC_ZX296702) selects PM_GENERIC_DOMAINS which has
unmet direct dependencies (PM)
warning: (ARCH_EXYNOS) selects EXYNOS_THERMAL which has unmet direct
dependencies (THERMAL && (ARCH_EXYNOS || COMPILE_TEST) && THERMAL_OF)
power/domain.c: In function 'genpd_queue_power_off_work':
power/domain.c:192:13: error: 'pm_wq' undeclared (first use in this
function)
  queue_work(pm_wq, &genpd->power_off_work);
             ^
power/domain.c:192:13: note: each undeclared identifier is reported only
once for each function it appears in

This ensures we don't try to enable it when CONFIG_PM is
disabled, mirroring what we do on most other platforms.

FYI.. Not sure what mailer you're using, but your "reviewd-by" tag (as
well as the first line of some of your other replies) are showing up in
the quoted section of the previous mail, so it's not obvious at first
glance which part is your reply, and which part you're replying to.
