keymile: Make distinct kmsupx5, tuge1, kmopti2, and kmtepr2 configs

The kmsupx5, tuge1, kmopti2, and kmtepr2 boards all build from the same
include config file with lots of #ifdef logic.

To ease Kconfig migration, create new config include files for these
boards, and resolve the #ifdef logic as needed.
