kernel-yocto: allow --allnoconfig and --alldefconfig as KCONFIG_MODES
Previously merge_config.sh was wrapped by the configme script, configme
took the different KCONFIG_MODES as options, and used --allnoconfig
or --alldefconfig.
With the switch to merge_config.sh no longer being wrapped, the new
processing wasn't matching the existing values and only supported
allnoconfig or alldefconfig.
To avoid breaking existing layers, and also keep any working that
have already switched, we can make the case statement match both.
