ipa: vimc: Add support for tracing operations
Add support to the dummy VIMC IPA for tracing operation by using a FIFO channel that will be used by the IPA Interface test to verify communications with the IPA. At the moment only add support for the init() operation as it's the only defined one. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>
