drm/fb-helper: implement ioctl FBIO_WAITFORVSYNC Implement legacy framebuffer ioctl FBIO_WAITFORVSYNC in the generic framebuffer emulation driver. Legacy framebuffer users like non kms/drm based OpenGL(ES)/EGL implementations may require the ioctl to synchronize drawing or buffer flip for double buffering. It is tested on the i.MX6.
