arch/x86/Kconfig: Add warning to config LATE_CBMEM_INIT help text

The deprecation of late (post-romstage) CBMEM initialization was
announced in this blog post:
https://blogs.coreboot.org/blog/2017/05/08/announcing-coreboot-4-6/

Arguably, extending the help text of CONFIG_LATE_CBMEM_INIT isn't very
useful because neither menuconfig nor nconfig show it for options
without a prompt. Therefore, I added warning to the mainboard menu.
