Subject: [PATCH 5.4 042/102] soc: qcom: llcc: Name regmaps to avoid collisions

From: Stephen Boyd <swboyd@...omium.org>

commit 2bfd3e7651addcaf48f12d4f11ea9d8fca6c3aa8 upstream.

We'll end up with debugfs collisions if we don't give names to the
regmaps created by this driver. Change the name of the config before
registering it so we don't collide in debugfs.

Fixes: 7f9c136216c7 ("soc: qcom: Add broadcast base for Last Level Cache Controller (LLCC)")
