The rework of the power domain code has made the genpd_poweron()
function local to the file it's defined in, and the only remaining
caller is conditionally compiled based on CONFIG_PM_GENERIC_DOMAINS_OF,
so we get a warning when that is disabled:

drivers/base/power/domain.c:234:12: error: 'genpd_poweron' defined but not used [-Werror=unused-function]

This adds a __maybe_unused annotation to the function so gcc can
figure out by itself that it should silently remove the definition
in this case.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Fixes: ea823c7cbffa ("PM / Domains: Remove pm_genpd_poweron() API")
