[PATCH -v2] fbdev: sh_mobile_meram: Fix defined but not used compiler warnings

[geert@linux-m68k.org (Geert Uytterhoeven)]

If both CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME are not set:

drivers/video/sh_mobile_meram.c:573: warning: ?sh_mobile_meram_suspend? defined but not used
drivers/video/sh_mobile_meram.c:597: warning: ?sh_mobile_meram_resume? defined but not used

Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

v2: Both functions are used if CONFIG_PM_SLEEP || CONFIG_PM_RUNTIME,
    as pointed out by Laurent
