linux-ls1: Apply kernel configs

Aplpy the same kernel configs as for the qoriq kernel. meta-fsl-arm has
a class overwriting the .config file in do_configure_prepend which makes
it impossible to make changes to it in a .bbappend. So we are forced to
change it in do_configure_append and force another configuration.
