drivers: Intel: SSP: fix update of DAI config in prepared state

The checks added in commit fc73578be774 ("drivers: Intel: SSP: ignore
config when SSP is already configured") also filter out cases where the
SSP parameters actually are modified in prepare state. This will happen
e.g. with a topology that has multiple configs for SSP and uses static
topology loading.

Modify the checks such that reconfiguration is done if:
 - the config is actually modified,
 - early MCLK/BCLK is not running.
