topology: imx8: add mixer component with cs42888 codec
This topology works on i.MX8QM and i.MX8QXP with cs42888 codec. When loaded, one will have a sound card with two playback subdevices. This way, samples pushed to the two subdevices will be mixed and sent to ESAI0 and then to cs42888 codec. Signed-off-by: Iuliana Prodan <iuliana.prodan@nxp.com>
