drm/msm/sde: add virtual writeback device and connector
Enable virtual writeback connector by allowing a property on the
connector to specify output frame buffer id, which takes in a
framebuffer object added via ADDFB2 ioctl. A new writeback
configure ioctl is added to configure connection state and
display modes of writeback connector.
