drivers/gpu/drm/drm_fb_helper.c: don't use private implementation of atoi()

Browse Source 
Kernel has simple_strtol() which would be used as atoi().

This is quite the same fix as in 2cb96f8662
("fbdev: drop custom atoi from drivers/video/modedb.c") because code in
drivers/gpu/drm/drm_fb_helper.c is based on drivers/video/modedb.c.
