da830: Move common code out of da830evm.c file

Browse Source 
TI's DA850/OMAP-L138 platform is similar to DA830/OMAP-L137
in many aspects. So instead of repeating the same code in
multiple files, move the common code to a different file
and call those functions from the respective da830/da850
files.
