Therefore document 8 as a valid option for spi-tx{rx}-bus-width

spi: Fix the number of CS lines documented as an example
...
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.

spi: dt-bindings: spi-controller: remove unnecessary 'maxItems: 1' from reg
...
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'.

spi: Add YAML schemas for the generic SPI options
...
The SPI controllers have a bunch of generic options that are needed in a
device tree. Add a YAML schemas for those.
