Have make_kconfig.pl output int config vars with their default value

From: Trent Piepho <xyzzy@speakeasy.org>

A few drivers have integer config variables defined in their Kconfig file
which must be set for them to compile.  make_kconfig.pl would just ignore int
variables and not put them into .config at all.  This change will put them
into .config set to their default values.
