fbcon: Add fbcon_rotate_hint to struct fb_info
On some hardware the LCD panel is not mounted upright in the casing, but upside-down or rotated 90 degrees. In this case we want the console to automatically be rotated to compensate. The fbdev-driver may know about the need to rotate. Add a new fbcon_rotate_hint field to struct fb_info, which gets initialized to -1. If the fbdev-driver knows that some sort of rotation is necessary then it can set this field to a FB_ROTATE_* value to tell the fbcon console driver to rotate the console.
