spi: spi-uclass: Read chipselect and restrict capabilities
Read chipselect properties from DT which are populated using 'reg'
property and save it in plat->cs[] array for later use.
Also read multi chipselect capability which is used for
parallel-memories and return errors if they are passed on using DT but
driver is not capable of handling it.
