[PATCH] fbcmap.c: mark structs const or __read_mostly
- Mark the default colormaps read-only, as nobody should be allowed to
modify them
- Additionally mark color values as __read_mostly since they will only be
modified (very seldom) by fb_invert_cmaps()
- Add named C99-initializers in fb_cmap structs and use the ARRAY_SIZE()
macro
