S5P_MIPI_DSIM is too long, I think DSIM is better than it.

Thank you for your comments and I will look forward to your next comments.

My actions is as the following.
1. corrected naming, (MIPI -> DSIM)
2. header files in plat-s5p would be moved to driver and also removed
unnecessary codes.
3. code clean.
