  arm64: dts: corstone1000: Add definitions for secondary CPU cores (2025-03-03 17:07:15 +0000)

----------------------------------------------------------------
Armv8 FVP/Vexpress/Juno updates for v6.15

The main and bulk of the addition this time is the support for the Arm
reference Morello System Development Platform (SDP).

The Morello architecture is an experimental extension to Armv8.2-A,
enhancing the AArch64 execution state with capabilities for fine-grained
memory protection and scalable software compartmentalization. However
these changes doesn't add any of the support for security enhancements.
This is mainly adding device tree support for Morello SDP.

The platform iteslf is shipped with ACPI firmware. However, since the
ACPI bindings for GPU, DPU, I2C, I2S,..etc are not well defined or not
provided in the shipped ACPI firmware, there is a need for the device
tree as alternative for the developers focusing on those features.

The CPU is called rainier, the architecture is Morello and the platform
is Morello SDP board. There is FVP equivalent of the same though they
are not completely in feature parity with the real hardware.

These changes provide the initial support for Morello SDP and FVP
platforms.

Apart from this, we have an update to add support for secondary cores
on Corstone1000 FVP platform.
