Last Level Cache (LLC) coloring allows to partition the cache in smaller chunks called cache colors. Since not all architectures can actually implement it, add a HAS_LLC_COLORING Kconfig option. LLC_COLORS_ORDER Kconfig option has a range maximum of 10 (2^10 = 1024) because that's the number of colors that fit in a 4 KiB page when integers are 4 bytes long. LLC colors are a property of the domain, so struct domain has to be extended.
