arch/x86/Kconfig: Add deprecation warnings for LATE_CBMEM_INIT
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/
There are two warnings:
* In LATE_CBMEM_INIT's help text, I've added a multi-line warning, that
aims to explain the problem.
* In src/mainboard/Kconfig (just below the mainboard selection), there's
a warning which points the user at LATE_CBMEM_INIT, if such a board is
selected.
Also update the function that needs to be implemented, as pointed out by
Keith Hui and Kyösti Mälkki.
