Subject: [PATCHv2] Make CONFIG_EXPERT select CONFIG_DEBUG_KERNEL to unhide
 debug options

Several debugging options currently default to y, such as
CONFIG_DEBUG_BUGVERBOSE and CONFIG_DEBUG_RODATA.  Embedded users might
want to turn those options off to save space; however, turning them off
requires turning on CONFIG_DEBUG_KERNEL to unhide them.  Since
CONFIG_DEBUG_KERNEL exists specifically to unhide debugging options, and
CONFIG_EXPERT exists specifically to unhide options potentially needed
by experts and/or embedded users, make CONFIG_EXPERT automatically imply
CONFIG_DEBUG_KERNEL.

v2: Add a comment explaining the select of DEBUG_KERNEL, as suggested by
Frederic Weisbecker.
