non-internal ETISS config options in "Allowed options"

[JoGei]

ETISS initialize exposes configuration options that are not used by the neither core nor architecture. This leads to false feedback to users implying such options exists "out of the box". Some examples:

• etiss.enable_dmi the "direct memory interface" seems to be something from for systemc wrapper of the CPUCore - no usage in standalone ETISS
• etiss.log_pc is only checked in the example bare etiss processor to activate an additional plugin
• vp.sw_binary_ram no usage, deprecated since existing SystemWrappers now rely on ELF files
• vp.sw_binary_rom ""

The ETISS-Core should only expose options that it can also handle. While options like etiss.log_pc are used in the example, the example should expose its "extending" features, but not the Core.
