Subject: [PATCH] PM / Domains: avoid unused function warning

The only caller of pm_genpd_present outside of CONFIG_PM_GENERIC_DOMAINS_OF
was removed, so we now get a warning when that is disabled:

drivers/base/power/domain.c:725:13: error: 'pm_genpd_present' defined but not used [-Werror=unused-function]

This moves the function definition inside of the #ifdef section.

Fixes: 8b55e55ee443 ("PM / Domains: Handle safely genpd_syscore_switch() call on non-genpd device")
