kconfig: simplify select-with-unmet-direct-dependency warning
This is an attempt to simplify the expressing printed by kconfig when a
symbol is selected but still has direct unmet dependency.
First, the symbol reverse dependency is split in sub-expression. Then,
each sub-expression is checked to ensure that it does not contains the
unmet dependency. This removes the false-positive symbols and fixed symbol
which already have the correct dependency. Finally, only the symbol
responsible of the "select" is printed, instead of its full dependency tree.
