2019-08-20spi: Fix the number of CS lines documented as an exampleManivannan Sadhasivam
The number of CS lines is mentioned as 2 in the spi-controller binding but however in the example, 4 cs-gpios are used. Hence fix that to mention 4.

2019-07-10spi: dt-bindings: spi-controller: remove unnecessary 'maxItems: 1' from regRob Herring
Mixing array constraints like 'maxItems' and string or integer value constraints like 'minimum' don't make sense. Also, with only value constraints, it is implied we have a single value. So lets remove 'maxItems: 1'.
