Subject: [PATCH AUTOSEL for 4.9 52/55] ARM: dts: NSP: Fix PPI interrupt types

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

[ Upstream commit 5f1aa51c7a1eef1c5a60b8334e32c89904964245 ]

Booting a kernel results in the kernel warning us about the following
PPI interrupts configuration:
[    0.105127] smp: Bringing up secondary CPUs ...
[    0.110545] GIC: PPI11 is secure or misconfigured
[    0.110551] GIC: PPI13 is secure or misconfigured

Fix this by using the appropriate edge configuration for PPI11 and
PPI13, this is similar to what was fixed for Northstar (BCM5301X) in
commit 0e34079cd1f6 ("ARM: dts: BCM5301X: Correct GIC_PPI interrupt
flags").

Fixes: 7b2e987de207 ("ARM: NSP: add minimal Northstar Plus device tree")
Fixes: 1a9d53cabaf4 ("ARM: dts: NSP: Add TWD Support to DT")
