The PL011 IP has 2 clock inputs for UART core/baud and APB bus. The
Thunder2 SoC is missing the core "uartclk". In this case, the Linux
driver uses single clock for both clock inputs. Let's assume that's how
the h/w is wired and make the DT reflect that.

Fixes, which might have practical impact, however things were broken for
long enough to justify pushing it regular path:
1. ARM Juno: shorten node names for thermal zones, because Linux drivers
have strict limit of 20 characters.
2. HiSilicon: correct size of GIC GICC address space and add missing
GICH and GICV spaces, add cache info to properly describe cache
topology and solve kernel boot warning.
Several cleanups:
1. Use capital "OR" for multiple licenses in SPDX.
2. Correct white-spaces for code readability.
3. Fix W=1 dtc compiler warnings, which should not have practical
impact for Amazon, APM, Cavium, Realtek, Socionext Uniphier and
Spreadtrum like:
- missing unit addresses,
- nodes not belonging to soc node,
- not using generic node names,
- few incorrect unit addresses.

The "arm,armv8-pmuv3" compatible is intended only for s/w models. Primarily,
it doesn't provide any detail on uarch specific events.
There's still remaining cases for CPUs without any corresponding PMU
definition and for big.LITTLE systems which only have a single PMU node
(there should be one per core type).

There is no "reg-names" property in the PCI bindings and the value does
not conform to Devicetree coding style (upper-case letters, space), so
assume this was copied from downstream.
This fixes dtbs_check warning:
thunder2-99xx.dtb: pcie@30000000: Unevaluated properties are not allowed ('reg-names' was unexpected)

The GICv3 ITS is an MSI controller, therefore its node name should be
'msi-controller'. The ITS node is also expected to have '#msi-cells'.
Add it on Thunder as there are no users. Thunder2 uses 'msi-parent', but
Robin says that should be 'msi-map' instead and I'm not sure what's
correct for it.
The unit-addresses of both the ITS and main GIC node on thunder2 are also
wrong, so fix them while we're here.

The 'arm,armv8' compatible string is only for software models. It adds
little value otherwise and is inconsistently used as a fallback on some
platforms. Remove it from those platforms.
This fixes warnings generated by the DT schema.

Move and update device tree files as part of transition from Broadcom
Vulcan to Cavium ThunderX2.
The changes are to:
* rename dts/broadcom/vulcan.dtsi to cavium/thunder2-99xx.dtsi,
update cpu cores to be "cavium,thunder2", and update SoC to be
"cavium,thunderx2-cn9900"
* move SoC dts/broadcom/vulcan-eval.dtsi to cavium/thunder2-99xx.dtsi
and update board name string
* Update dts/broadcom/Makefile not to build vulcan dtbs
* Update dts/cavium/Makefile to build thunder2 dtbs
No changes to the dts contents except the updated "compatible" and
"model" properties.
