When running "make dt_binding_check" (even if restricted to an unrelated
binding document using DT_SCHEMA_FILES=...):
Documentation/devicetree/bindings/spi/spi-fsl-lpspi.yaml: ignoring, error in schema: properties: fsl,spi-only-use-cs1-sel
warning: no schema found in file: Documentation/devicetree/bindings/spi/spi-fsl-lpspi.yaml
Fix this by adding a proper type definition for the vendor-specific
fsl,spi-only-use-cs1-sel property.
Fixes: 7ac9bbf6ab ("dt-bindings: lpspi: New property in document DT bindings for LPSPI")

Add "fsl,spi-only-use-cs1-sel" to fit i.MX8DXL-EVK.
Spi common code does not support use of CS signals discontinuously.
It only uses CS1 without using CS0. So, add this property to re-config
chipselect value.
