using compatible string.

In case of error, the function syscon_regmap_lookup_by_phandle() returns
ERR_PTR() and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().

here are the changes to enable player tdm mode:
- When TDM_ENABLE is set to 1, the i2s format should be automatically
configured. Unfortunately this is not the case (HW bug). Then, we shall
force DATA_SIZE setting.
- Compute the transfer size for tdm mode: transfer size = user frame size
- Manage tdm slots configuration given in DT.
- Don't use mclk-fs when unip in tdm mode; use tdm slot config to compute
frame size and to set mclk rate.
- Refine the hw param (channels & format) according to tdm slot config.

Previously, the iec958 channels status sampling freq was set only if not
already set. It means that it is not updated for next PCM sessions.
With this patch, we ensure the iec958 channels status sampling freq is set
to the runtime rate for each PCM session.
