[PATCH linux dev-4.10 v2 2/3] ARM: dts: fsi: Add optional master property no-scan-on-init

Add new optional master property no-scan-on-init that specifies
that at master init time it should not scan for connected devices.
This is necessary in cases where a scan could interfere with
other connected FSI masters on the same bus.
