common: convert compulab splash load code to common code
Move board/compulab/common/splash.c code to
common/splash_source.c to make it available for everybody. This move
renames cl_splash_screen_prepare() to splash_source_load(), and
the compilation of this code is conditional on CONFIG_SPLASH_SOURCE.
splash_source features:
* Provide a standardized way for declaring board specific splash screen
locations
* Provide existing routines for auto loading the splash image from the
locations as declared by the board
* Introduce the "splashsource" environment variable, which makes it
possible to select the splash image source.
cm-t35 and cm-fx6 are updated to use the modified version.
