Trent Piepho 59faba1b31 Fix Kconfig dependency problems wrt boolean menuconfigs
If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on
(tristate)BAZ, build problems will result.  If BAZ=m, then BAR can be set
y, which allows FOO=y.  It's possible to have FOO=y && BAZ=m, which
wouldn't be allowed if FOO depended directly on BAZ.  In effect, the bool
promotes the tristate from m to y.

This ends up causing a problem with several menuconfigs that look like:

menuconfig BAR
	bool
	depends on BAZ [tristate]
if BAR
config FOO
	tristate
endif

The solution used here is to add the dependencies of BAR to the if
statement, so that items in the if block will gain a direct
non-bool-promoted dependency on BAZ.  This is how it would work if a menu
was used instead of an if block.
