soc: amlogic: fix compile failure with MESON_SECURE_PM_DOMAINS & !MESON_SM

When MESON_SECURE_PM_DOMAINS & !MESON_SM, there will be compile failure:
.../meson-secure-pwrc.o: In function `meson_secure_pwrc_on':
.../meson-secure-pwrc.c:76: undefined reference to `meson_sm_call'

Fix this by adding depends on MESON_SM for MESON_SECURE_PM_DOMAINS.
