arm64: tegra: Disable Tegra234 sce-fabric node

commit a5e6fc0a10fe280989f1367a3b4f8047c7d00ea6 upstream.

Access to safety cluster engine (SCE) fabric registers was blocked
by firewall after the introduction of Functional Safety Island in
Tegra234. After that, any access by software to SCE registers is
correctly resulting in the internal bus error. However, when CPUs
try accessing the SCE-fabric registers to print error info,
another firewall error occurs as the fabric registers are also
firewall protected. This results in a second error to be printed.
Disable the SCE fabric node to avoid printing the misleading error.
The first error info will be printed by the interrupt from the
fabric causing the actual access.

arm64: tegra: Fix typo in Tegra234 dce-fabric compatible

arm64: tegra: Fix typo in Tegra234 dce-fabric compatible

commit 604120fd9e9df50ee0e803d3c6e77a1f45d2c58e upstream.

The compatible string for the Tegra DCE fabric is currently defined as
'nvidia,tegra234-sce-fabric' but this is incorrect because this is the
compatible string for SCE fabric. Update the compatible for the DCE
fabric to correct the compatible string.

This compatible needs to be correct in order for the interconnect
to catch things such as improper data accesses.

arm64: tegra: Fix Tegra234 PCIe interrupt-map

arm64: tegra: Fix Tegra234 PCIe interrupt-map

commit b615fbd70fce8582d92b3bdbbf3c9b80cadcfb55 upstream.

For interrupt-map entries, the DTS specification requires
that #address-cells is defined for both the child node and the
interrupt parent. For the PCIe interrupt-map entries, the parent
node ("gic") has not specified #address-cells. The existing layout
of the PCIe interrupt-map entries indicates that it assumes
that #address-cells is zero for this node.

Explicitly set #address-cells to zero for "gic" so that it complies
with the device tree specification.

NVIDIA EDK2 works around this issue by assuming #address-cells
is zero in this scenario, but that workaround is being removed and so
this update is needed or else NVIDIA EDK2 cannot successfully parse the
device tree and the board cannot boot.
