Subject: [PATCH RFC 5/9] arm64: dts: rockchip: rk1808k-toybrick-m0: Suppress vGIC interrupt

Avoid the kernel getting stuck after:

[    1.175956] kvm [1]: IPA Size Limit: 40 bits
[    1.177164] kvm [1]: vgic-v2@...20000
[    1.177545] kvm [1]: GIC system register CPU interface enabled

or when dropping GICV reg entry:

[    1.176001] kvm [1]: IPA Size Limit: 40 bits
[    1.177191] kvm [1]: GICv3: no GICV resource entry
[    1.177664] kvm [1]: disabling GICv2 emulation
[    1.178115] kvm [1]: GIC system register CPU interface enabled
