topology: Add topology for i.MX8QXP with cs42888 codec 

This pipeline adds support for S24_LE, 2 channels, 48KHz playback.

cs42888 codec is connected to i.MX8QXP board on ESAI0 interface
as follows:
i.MX8QXP CPU board <--> i.MX8 base board <-> Audio I/O card
(setup similar with i.MX8QM, so this topology can be used as it is
on i.MX8QM in the future).
