mb/{razer,purism}: Don't select NO_POST

The NO_POST option covers more than classical port 80 output, hence
selecting it seems wrong in any case. The default is still rather
user patronizing, but let's keep it.

As a side effect, this fixes the ability to override the default
for NO_POST which Kconfig rejected while these boards selected it.
(Seems like a bug in Kconfig, though.)
