dt-bindings: fsi: Add optional property no-scan-on-init
Add an optional FSI master property 'no-scan-on-init. This
can be specified to indicate that a master should not be
automatically scanned at init time. This is required in cases
where a scan could interfere with another FSI master on the same
bus.
