Subject: [PATCH] net: systemport: fix unused function warning

The only remaining caller of this function is inside of an #ifdef
after another caller got removed. This causes a harmless warning
in some configurations:

drivers/net/ethernet/broadcom/bcmsysport.c:1068:13: error: 'bcm_sysport_resume_from_wol' defined but not used [-Werror=unused-function]

Removing the #ifdef around the PM functions simplifies the code
and avoids the problem but letting the compiler drop the unused
functions silently.

Fixes: 9e85e22713d6 ("net: systemport: Do not re-configure upon WoL interrupt")
