ENGR00221444 HDMI: video mode wrong when bootup without HDMI cable
Bootup Android without HDMI cable plugin, then plugin HDMI cable,
video mode in /sys/class/graphics/fb0/mode not same as actually
HDMI work video mode.
The root cause is in video mode point to one of video mode in
original video modelist, but the modelist will be updated when
HDMI cable plug to new monitor.
If HDMI original worked video mode can work on new monitor,
the HDMI and framebuffer will not updated, so HDMI actually
work mode not same as /sys/class/graphics/fb0/mode
Updated fbi mode pointer even if video mode no changed
in case moselist is updated, the issue will fixed.
