Subject: [PATCH v2 06/15] drm/sun4i: sun6i_mipi_dsi: Add DSI Generic short write 2 param transfer

Short transfer write support for DCS and Generic transfer types
share similar way to process command sequence in DSI block so
add generic write 2 param transfer type macro so-that the panels
which are requesting similar transfer type may process properly.

Signed-off-by: Jagan Teki <jagan@...rulasolutions.com>

Changes for v2:
- drop dev_err
- add macro in alphabetical
