Subject: [PATCH 5.4 09/61] ARM: dts: imx6qdl-gw52xx: fix duplicate regulator naming

From: Koen Vandeputte <koen.vandeputte@...ymesh.com>

commit 5a22747b76ca2384057d8e783265404439d31d7f upstream.

2 regulator descriptions carry identical naming.

This leads to following boot warning:
[    0.173138] debugfs: Directory 'vdd1p8' with parent 'regulator' already present!

Fix this by renaming the one used for audio.
