Convert the UniPhier GPIO controller binding to DT schema format.

I omitted the 'gpio-ranges' property because it is defined in the

As of writing, the 'gpio-ranges-group-names' is not defined in that
file despite it is a common property described in
Documentation/devicetree/bindings/gpio/gpio.txt

Some tests in the devicetree unittests result in printk messages
from the code being tested.  It can be difficult to determine
whether the messages are the result of unittest or are potentially
reporting bugs that should be fixed.  The most recent example of
a person asking whether to be concerned about these messages is [1].

Add annotations for all messages triggered by unittests, except
KERN_DEBUG messages.  (KERN_DEBUG is a special case due to the
possible interaction of CONFIG_DYNAMIC_DEBUG.)

The format of the annotations is expected to change when unittests
are converted to use the kunit infrastructure when the broader
testing community has an opportunity to discuss the implementation
of annotations of test triggered messages.

Geert reports that gpio hog nodes are not properly processed when
the gpio hog node is added via an overlay reply and provides an
RFC patch to fix the problem [1].

Add a unittest that shows the problem.  Unittest will report "1 failed"
test before applying Geert's RFC patch and "0 failed" after applying
Geert's RFC patch.

Certain SoCs need to support a large amount of reserved memory
regions. For example, Qualcomm's SM8150 SoC requires that 20
regions of memory be reserved for a variety of reasons (e.g.
loading a peripheral subsystem's firmware image into a
particular space).

When adding more reserved memory regions to cater to different
usecases, the remaining number of reserved memory regions--12
to be exact--becomes too small. Thus, double the existing
limit of reserved memory regions.

The "alpha by vendor, reverse-alpha by model" sorting of compatibles
that we seem to have ended up with is decidedly odd. Make it less so.

Also copy the comment from the generic "arm,armv8" CPU binding to help
clarify that the "arm,armv8-pmuv3" binding is rather intended to be a
counterpart to that, for describing implementations without a specific
microarchitecture like the AEMv8 software model.

Currently, the DMA offset and mask for a device are set based only on the
first 'dma-ranges' entry. We should really be using all the entries. The
kernel doesn't yet support multiple offsets and sizes, so the best we can
do is to find the biggest size for a single offset. The algorithm is
copied from acpi_dma_get_range().

If there's different offsets from the first entry, then we warn and
continue. It really should be an error, but this will likely break
existing DTs.

of_dma_get_range() does the same ranges parsing as

than the 1st dma-ranges entry.

The only PCI specific part of of_pci_range_parser_one() is the handling

helpers and struct.
