Fix up remaining boolean uses of CONFIG_XXX to CONFIG(XXX)

This patch cleans up remaining uses of raw boolean Kconfig values I
could find by wrapping them with CONFIG(). The remaining naked config
value warnings in the code should all be false positives now (although
the process was semi-manual and involved some eyeballing so I may have
missed a few).
