This patch adds MIPI-DSI based S6E63J0X03 AMOLED LCD panel driver
which uses mipi_dsi bus to communicate with panel. The panel has
320×320 resolution in 1.63-inch physical panel. This panel is used in
Samsung Galaxy Gear 2.

Changes for v2:
- Change the gamma table to 2-dimensional array
- Change the way to make index for brightness
- Make command functions to an array so that it can be called simply
- Change command id for reading device ID
- Change the way to handle the error condition
- Remove power variable, and use the same name variable in bl_dev
- Add the state FB_BLANK_NORMAL to represent the state which the panel
is working but blanked
- Miscellaneous changes to increase the readability and follow the
coding-style standard
