projects/WeTek_Core: Switch to "hotplug" CPU scaling governor

Browse Source 
Many WeTek Core users have been experiencing major UI lag issues when
using the "ondemand" governor.  If left inactive for a period of time,
the UI becomes extremely sluggish and a reboot is required.

Users did not experience this issue with LE 7.  The switch from the
"performance" to "interactive" governor was made in revision 8610fb3270
("projects/WeTek_Core: Use interactive CPU scaling governor by
default").  Users then started experiencing the UI issues, and revision
c908c1f453 ("projects/WeTek_Core: Switch to ondemand CPU scaling
governor") attempted to address the problem.  Unfortunately, this did
not appear to resolve the issue.

After switching to "hotplug", users could not replicate the UI lag
issues anymore.
