firmware: cirrus: cs_dsp: Initialize debugfs_root to invalid

Browse source

[ Upstream commit 66626b1563 ]

Initialize debugfs_root to -ENODEV so that if the client never sets a
valid debugfs root the debugfs files will not be created.

A NULL pointer passed to any of the debugfs_create_*() functions means
"create in the root of debugfs". It doesn't mean "ignore".
