drm/bridge/synopsys: dsi: Register list clean up
This patch cleans up the Synopsys mipi dsi register list: - rename registers according to the Synopsys documentation (1.30 & 1.31) - fix typos - re-order registers for a better coherency Signed-off-by: Philippe CORNU <philippe.cornu@st.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Archit Taneja <architt@codeaurora.org> Link: https://patchwork.freedesktop.org/patch/msgid/1501593788-21036-3-git-send-email-philippe.cornu@st.com
