Subject: [PATCH 4.14 121/156] ARM: dts: NSP: Disable AHCI controller for HR NSP boards

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Florian Fainelli <f.fainelli@...il.com>


[ Upstream commit 77416ab35f5712382e5a792bfa1736ceb70d5bbb ]

The AHCI controller is currently enabled for all of these boards:
bcm958623hr and bcm958625hr would result in a hard hang on boot that we
cannot get rid of. Since this does not appear to have an easy and simple
fix, just disable the AHCI controller for now until this gets resolved.

Fixes: 70725d6e97ac ("ARM: dts: NSP: Enable SATA on bcm958625hr")
Fixes: d454c3762437 ("ARM: dts: NSP: Add new DT file for bcm958623hr")
