Charles Mirabile 0129dfe7bf irqchip/gic-v3: Fix rk3399 workaround when secure interrupts are enabled 
JIRA: https://issues.redhat.com/browse/RHEL-62922

commit 4cb77793842a351b39a030f77caebace3524840e
Author: Marc Zyngier <maz@kernel.org>
Date: Sat, 15 Feb 2025 18:52:41 +0000

    Christoph reports that their rk3399 system dies since commit 773c05f417fa1
    ("irqchip/gic-v3: Work around insecure GIC integrations").

    It appears that some rk3399 have secure payloads, and that the firmware
    sets SCR_EL3.FIQ==1. Obivously, disabling security in that configuration
    leads to even more problems.

    Revisit the workaround by:

      - making it rk3399 specific
      - checking whether Group-0 is available, which is a good proxy
        for SCR_EL3.FIQ being 0
      - either apply the workaround if Group-0 is available, or disable
        pseudo-NMIs if not

    Note that this doesn't mean that the secure side is able to receive
    interrupts, as all interrupts are made non-secure anyway.

    Clearly, nobody ever tested secure interrupts on this platform.

    Fixes: 773c05f417fa1 ("irqchip/gic-v3: Work around insecure GIC integrations")
