This patch:
 * fixes various mistakes (leading spaces, wrong or missing model names)
 * shortens model strings (we don't need to use whole model string from dts file, make it for consistency and as optimization)
 * sorts boards alphabetically

in base-files/lib/ramips.sh script.

Case statement was tested after above changes with simple script, which:
 * takes model string from dts{,i} file (model = "...")
 * provides this value as case input ($machine)
 * returns output ($name)
