There are two menu entries for X86_EXTENDED_PLATFORM, one for X86_32
and the other for X64_64.
These entries are nearly identical, with the only difference being
the platform list in the help message.
While I know this structure was intended by commit 8425091ff8af ("x86:
improve the help text of X86_EXTENDED_PLATFORM"), IMHO there is no need to
duplicate the entire config entry. Instead, we can provide a little more
clarification in the help message.

x86/Kconfig: Merge the two CONFIG_X86_EXTENDED_PLATFORM entries
There are two menu entries for X86_EXTENDED_PLATFORM, one for X86_32 and
the other for X86_64.
These entries are nearly identical, with the only difference being the
platform list in the help message.
While this structure was intended by commit
8425091ff8af ("x86: improve the help text of X86_EXTENDED_PLATFORM"),
there is no need to duplicate the entire config entry. Instead, provide
a little more clarification in the help message.
