RK3288 only supports rotation at the display level (i.e. CRTC), but for now we are only interested in plane rotation. This commit only adds support for the value of reflect-y and reflect-x (i.e. mirroring). Note that y-mirroring is not compatible with YUV. The following modetest commands would test this feature, where 30 is the plane ID, and 49 = rotate_0 + relect_y + reflect_x.
