dt-bindings: nfc: ti,trf7970a: Restrict the ti,rx-gain-reduction-db values
...
Instead of stating the supported values for the ti,rx-gain-reduction-db
property in free text format, add an enum entry that can help validating
the devicetree files.

dt-bindings: nfc: ti,trf7970a: Drop 'db' suffix duplicating dtschema
...
A common property unit suffix '-db' was added to dtschema, thus
in-kernel bindings should not reference the type.

dt-bindings: nfc: use spi-peripheral-props.yaml
...
Instead of listing directly properties typical for SPI peripherals,
reference the spi-peripheral-props.yaml schema. This allows using all
properties typical for SPI-connected devices, even these which device
bindings author did not tried yet.
Remove the spi-* properties which now come via spi-peripheral-props.yaml
schema, except for the cases when device schema adds some constraints
like maximum frequency.
While changing additionalProperties->unevaluatedProperties, put it in
typical place, just before example DTS.
