dt-bindings: snps,dw-apb-ssi: Add mandatory clock bindings documentation
The Synopsys SSI driver uses a mandatory clock that is not documented,
so detail it in the device tree bindings. Also correct the spelling of
"pins" in the "Optional Properties" section for the driver.

Optional properties:
-- cs-gpios : Specifies the gpio pis to be used for chipselects.
+- cs-gpios : Specifies the gpio pins to be used for chipselects.
- num-cs : The number of chipselects. If omitted, this will default to 4.

device. Supported values are 2 or 4 (the default).
