kill POHIC-G/S deployment view for MSP430

Michał's fork of the C++ runtime for x86 Linux is the only one we got to
work so far. maybe this is just because of print_service, maybe not, but
it's not broken, so why fix it? instead, let's promote it to our
default:
- rename deploymentview_cpp.dv.xml to deploymentview.dv.xml
- rename deploymentview_cpp.ui.xml to deploymentview.ui.xml
- delete deploymentview_pohic.dv.xml and deploymentview_pohic.ui.xml
