From 3dd97e70450f899bad68f348e5be94c68a2f7b72 Mon Sep 17 00:00:00 2001
From: Jonathan Bell <jonathan@raspberrypi.com>

Subject: [PATCH 0854/1085] dts: rp1: nobble HS and FS/LS park mode for dwc3
xhci
Synopsys have recommended that we disable this feature entirely, as
Superspeed park mode can hang the controller, and Hs/FS/LS park mode can
cause performance degradation with bursty devices.
