[why] We have seen a green screen after resume from suspend in a Raven system connected with two displays (HDMI and DP) on X based system. We noticed that this issue is related to bad DCC metadata from user space which may generate hangs and consequently an underflow on HUBP. After taking a deep look at the code path we realized that after resume we try to restore the commit with the DCC enabled framebuffer but the framebuffer is no longer valid. [how] This problem was only reported on Raven based system and after suspend, for this reason, this commit adds a new parameter on fill_plane_dcc_attributes() to give the option of disabling DCC programmatically. In summary, for disabling DCC we first verify if is a Raven system and if it is in suspend; if both conditions are true we disable DCC temporarily, otherwise, it is enabled.
