drm/omap: fix pitch round-up
At the moment we calculate the buffer's pitch with:
pitch = width * DIV_ROUND_UP(bpp, 8)
For CLUT modes with bpp of 1/2/4/8 this gives wrong result, and the
correct pitch is:
pitch = DIV_ROUND_UP(width * bpp, 8)
In practice this doesn't change anything, as we don't support CLUT
modes, but it's better to have the pitch calculation correct.
