Makefile: Allow platform to provide additional params for add cmd

This change adds optional CBFSTOOL_ADD_CMD_OPTIONS that can be used by
arch/SoC/mainboard Makefiles to supply any additional arguments that
need to be passed into cbfstool when using cbfstool add command.
This is useful when platform wants to add these parameters depending
upon some arch/SoC/mainboard specific configs. Immediate use case is
the fast SPI controller on Intel platforms adding arguments for
extended window base and size.
