drivers: dai: intel: ssp: Ignore TX/RX or DMA request enable bits from blob

When loading the SSP configuration from a blob ignore the bits which would
enable the TX/RX or DMA requests at configuration phase.

The TX/RX enable and DMA request is handled by the driver itself. If the
blob wrongly enables any of the bits can have runtime (startup time)
seemingly random issues.
