dts: renamed FIT_EMBED to MULTI_DTB_FIT and moved it to the dts Kconfig
CONFIG_FIT_EMBED might be confused with CONFIG_OF_EMBED, rename it MULTI_DTB_FIT as it is able to get a DTB from a FIT image containing multiple DTBs. Also move the option to the Kconfig dedicated to the DTS options and create a README for this feature.
