Commit 6a108a14 ("kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT")
introduces CONFIG_EXPERT to carry the previous intent of CONFIG_EMBEDDED
and just gives that intent a much better name. That has been clearly a good
and long overdue renaming, and it is clearly an improvement to the kernel

configuration in the last decade.

However, rather than bravely and radically just deleting CONFIG_EMBEDDED,
this commit gives CONFIG_EMBEDDED a new intended semantics, but keeps it
open for future contributors to implement that intended semantics:

    A new CONFIG_EMBEDDED option is added that automatically selects
    CONFIG_EXPERT when enabled and can be used in the future to isolate
    options that should only be considered for embedded systems (RISC
    architectures, SLOB, etc).

Since then, this CONFIG_EMBEDDED implicitly had two purposes:

  - It can make even more options ...
