Add missing address-cells 0 to GIC interrupt node to silence W=1
warning:
alpine-v3.dtsi:342.4-349.33: Warning (interrupt_map): /soc/pcie@fbd00000:interrupt-map:
Missing property '#address-cells' in node /soc/interrupt-controller@f0800000, using 0 as fallback
Value '0' is correct because:
1. GIC interrupt controller does not have children,
2. interrupt-map property (in PCI node) consists of five components and
the fourth component "parent unit address", which size is defined by
'#address-cells' of the node pointed to by the interrupt-parent
component, is not used (=0)

Minor improvements in ARM64 DTS for v6.10
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.
