VIA/WonderMedia SoC's have a chip ID register inside their system
configuration controller space, which can be used to identify
appropriate hardware quirks at runtime. Add binding for it.

Add "samsung,exynos2200-chipid" compatible string to binding document.
Since Samsung, as usual, likes reusing devices from older designs, use
the samsung,exynos850-chipid compatible.

existing SoC
Samsung Exynos SoC reuses several devices from older designs, thus
historically we kept the old (block's) compatible only. This works fine
and there is no bug here, however guidelines expressed in
Documentation/devicetree/bindings/writing-bindings.rst state that:
1. Compatibles should be specific.
2. We should add new compatibles in case of bugs or features.
Add compatibles specific to each SoC in front of all old-SoC-like
compatibles.

Pull devicetree updates from Rob Herring:
"Bindings:
- Add spi-peripheral-props.yaml references to various SPI device
bindings
- Convert qcom,pm8916-wdt, ds1307, Qualcomm BAM DMA, is31fl319x,
skyworks,aat1290, Rockchip EMAC, gpio-ir-receiver, ahci-ceva, Arm
CCN PMU, rda,8810pl-intc, sil,sii9022, ps2-gpio, and
arm-firmware-suite bindings to DT schema format
- New bindings for Arm virtual platforms display, Qualcomm IMEM
memory region, Samsung S5PV210 ChipID, EM Microelectronic EM3027
RTC, and arm,cortex-a78ae
- Add vendor prefixes for asrock, bytedance, hxt, ingrasys, inventec,
quanta, and densitron
- Add missing MSI and IOMMU properties to host-generic-pci
- Remove bindings for removed EFM32 platform
- Remove old chosen.txt binding (replaced by schema)
- Treewide add missing type information for properties
- Treewide fixing of typos and its vs. it's in bindings. Its all good
now.
- Drop unnecessary quoting in power related schemas
- Several LED binding updates which didn't get picked up
- Move various bindings to proper directories
DT core code:
- Convert unittest GPIO related tests to use fwnode
- Check ima-kexec-buffer against memory bounds
- Print reserved-memory allocation/reservation failures as errors
- Cleanup early_init_dt_reserve_memory_arch()
- Simplify of_overlay_fdt_apply() tail"
