MLK-18585 video: fb: sii902x: Only bind to first mxs-lcdif FB
This driver registers itself as a fb_client and handles notifications
from all FB in the system.
It can end up trying to call fb_draw_logo on an overlay FB and this will
crash because overlay_fb_ops has no fb_imageblit function.
It also handles blank/unblank indiscriminately and for example if you
connect a second LVDS display on 6sx and blank/unblank it then HDMI will
also incorrectly blank/unblank. This last issue even affects imx_4.9.y
Fix by only processing notifications from the FB that it's bound to.
Bind to the first FB whose name starts with "mxs-lcdif" by checking
fb_info->fix.id on FB_EVENT_FB_REGISTERED.
