Don't need to do suspend/resume for fbcon in graphic mode.
Doing this may cause error, eg:
At the beginning, starting the Xorg with single screen and then an
external screen was plugged in. After logging out in Xorg, fbdev
info may using screen which is connected later on for info always
using first connected connector in list in func 'drm_setup_crtcs_fb'.
Then, S3 executed, fbcon found that the information did not match
and do atomic to switch fb. However, Xorg will not re-bind the crtc
fb but continues doing ioctl. At this time, the fb is incorrect.
