Subject: [PATCH 5.17 0768/1126] pinctrl: ocelot: fix duplicate debugfs entry

From: Michael Walle <michael@...le.cc>

[ Upstream commit 359afd90fef3ec9285432f50720c813987df4a89 ]

This driver can have up to two regmaps. If the second one is registered
its debugfs entry will have the same name as the first one and the
following error will be printed:

[    2.242568] debugfs: Directory 'e2004064.pinctrl' with parent 'regmap' already present!

Give the second regmap a name to avoid this.
