ANDROID: interconnect: Enable debugfs client

The interconnect debugfs client supports voting for any path registered
with the framework from shell, which is important for debugging and
testing.

This is normally disabled by default since directly touching bus HW from
user space can introduce security issues. However, Android already
considers debugfs itself unsafe and doesn't allow mounting it on user
devices anyway.

A similar approach was taken to enable writable debugfs files for the
clock framework in commit 861a024589 ("ANDROID: clk: Enable writable
debugfs files").
