Add a compatible string and clock mapping table to support ASRC on the
i.MX952 platform.

The clock mapping table is to map the clock sources on i.MX952 to the
clock ids in the driver, the clock ids are for all the clock sources on
all supported platforms.

At this point imx952 has the issue with dma request not cleared you fix
in patch 3/4.

So in order to avoid this you need to swap patches 2 and 3.  And in the
newly patch 3 you will fill fsl_asrc_imx952_data with correct value
for start_before_dma.

Thus we also keep everything working for bisection.

Good catch. I will swap them.
