spi: dt-bindings: support devices with multiple chipselects
Add binding support for devices, that have more than one
chip select. A typical example are SPI connected microcontroller,
that can also be programmed over SPI like NXP Kinetis or
chips with a configuration and a data chip select, such as
Microchip's MRF89XA transceiver.
