The QSPI controller needs three clock items to work properly on StarFive
JH7110 SoC, so there is need to change the maxItems's value to 3.

The QSPI controller needs three reset items to work properly on JH7110 SoC,
so there is need to change the maxItems's value to 3 and add minItems
whose value is equal to 2. Other platforms do not have this constraint.

Cleanup examples:
- use 4-space indentation (for cases when it is neither 4 not 2 space),
- drop redundant blank lines,
- use lowercase hex.
No functional impact except adjusting to preferred coding style.

Emails to Pratyush Yadav bounce ("550 Invalid recipient"). Generic SPI
properties should be maintained by subsystem maintainer (Mark). Add
recent contributor Vaishnav Achath to the Cadence SPI bindings.

Pull spi updates from Mark Brown:
"This has mostly been a quiet release for the SPI subsystem, almost all
cleanups and fixes to existing drivers.
A couple of changes that stand out:
- Cleanups and support for version specific features in the
DesignWare controller.
- Removal of support for Netlogic devices from the XLP driver, the
platform had previously been removed by MIPS so the support
couldn't be used.
- Conversion of several DT bindings to YAML format"

The QSPI controller on Intel's SoCFPGA platform does not implement the
CQSPI_REG_WR_COMPLETION_CTRL register, thus a write to this register
results in a crash.
Introduce the dts compatible "intel,socfpga-qspi" to differentiate the
hardware.

v3: revert to "intel,socfpga-qspi"
v2: change binding to "cdns,qspi-nor-0010" to be more generic for other
platforms

The spi-peripheral-props.yaml schema contains peripheral-specific
properties for SPI controllers that should be present in the peripheral
node. Move peripheral-specific properties to a separate file and refer
to it in spi-peripheral-props.yaml.

There is no way as of now to have a parent or bus defining properties
for child nodes. For now, avoid it in the example to silence warnings on
dt_schema_check. We can figure out how to deal with actual dts files
later.
[p.yadav@ti.com: Fix how compatible is defined, make reset optional, fix
minor typos, remove subnode properties in example, update commit
message.]
