arm-bsp/u-boot: update CS1K append to use the _config functions

The u-boot recipe now uses unique build directories per config that is
being built, to ensure that there is no cross-contamination.

Handle this by moving the do_configure and do_install appends to
uboot_configure_config and uboot_install_config so that we can simply
use $builddir.
