Marc Zyngier 773c05f417 irqchip/gic-v3: Work around insecure GIC integrations 
It appears that the relatively popular RK3399 SoC has been put together
using a large amount of illicit substances, as experiments reveal that its
integration of GIC500 exposes the *secure* programming interface to
non-secure.

This has some pretty bad effects on the way priorities are handled, and
results in a dead machine if booting with pseudo-NMI enabled
(irqchip.gicv3_pseudo_nmi=1) if the kernel contains 18fdb6348c ("arm64:
irqchip/gic-v3: Select priorities at boot time"), which relies on the
priorities being programmed using the NS view.

Let's restore some sanity by going one step further and disable security
altogether in this case. This is not any worse, and puts us in a mode where
priorities actually make some sense.

Huge thanks to Mark Kettenis who initially identified this issue on
OpenBSD, and to Chen-Yu Tsai who reported the problem in Linux.

Fixes: 18fdb6348c ("arm64: irqchip/gic-v3: Select priorities at boot time")
