AP_HAL: use default storage for more boards

Boards from Emlid, Erle Robotics and BBB-like ones were agreed to be
changed #7100. Here I'm also change some more, just because they appear
to be using the old default just because of copy and paste. We can
always revert back if we get complains and it seems something trivial.
Almost all boards now are using the the default path for logs, terrain
and params, except those that have restrictions to do so, like ones
using custom distros.
