ast2400: externalize revision numbers 

AST2400_A0_SILICON_REV is defined twice. Fix this by including the
definition in the header file as well as the routine to check if a
silicon revision is supported. It will useful to reuse in other
controllers.

Let's add also AST2500_A0_SILICON_REV for future use.
