[PATCH 11/13] dt-bindings: lpspi: Update maximum num-cs value

[James Clark <james.clark@linaro.org>]

As mentioned in commit f46b06e62c86 ("spi: spi-fsl-lpspi: Read
chip-select amount from hardware for i.MX93"), some devices support up
to 3 chip selects so update the max value.

This isn't a fix or functional change because the devices with 3 chip
selects support reading the number of chip selects from hardware, so the
value wouldn't have needed to be set here. However the commit states
that the DT could be used to overwrite any HW value, so the full range
should be supported. This also avoids confusion for any readers about
how many chip selects there are.
