Subject: [PATCH v2 1/2] soc: qcom: llcc: Name regmaps to avoid collisions

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)")
