This patch series converts atmel-flexcom bindings into json-schema format.
Adds support for lan966x flexcom chip-select configurations and its
DT bindings.

v8 -> v9:
- generated patches on linux-next v6.0.0-rc4 to resend.
- Changed reference provided for spi bindings to atmel,at91rm9200-spi.yaml

v7 -> v8:
- Added back patternProperties for child nodes.
- Changed compatible string to microchip,lan9668-flexcom.

v6 -> v7:
- Change filename to atmel,sama5d2-flexcom.yaml
- Add #address-cells, #size-cells to flexcom node - Fixed warnings.

v5 -> v6:

Once this is accepted, I will add back spi example through new patch.

v4 -> v5:
- Fix indentations of DT example.
- Fix dt-schema errors - removed minItems, maxItems for allOf:if:then
"reg" property as it is not required.

v3 -> v4:
- Fix dtschema errors.
- Add a condition to flexcom chip-selects configuration as chip-select
lines are optional.

v2 -> v3:
- changed IRQ flag in dt-bindings example.
- added reg property specific to lan66x which is missed in v2.
- used goto label for clk_disable in error cases.

v1 -> v2:
- minor fix in title of dt-bindings.
- Modified new dt properties usage in atmel,flexcom.yaml.
- Used GENMASK and macros for maximum allowed values.
- Use u32 values for flexcom chipselects instead of strings.
- disable clock in case of errors.
