Most uses of EXPERT are in the form
bool "something" if EXPERT
but some are
depends on EXPERT
The difference is the the 'depends on' use makes it
easier to select the CONFIG_EXPERT option.
$ git grep "if EXPERT" -- "*/Kconfig*" | wc -l
155
$ git grep "depends on.*EXPERT" -- "*/Kconfig*" | wc -l
26
Some of the 'depends on' uses with EXPERT are more menus
or complex logic with || and can not easily be modified,
but it's perhaps reasonable to modify the simpler ones
to the "if EXPERT" form.
