drivers: dai: intel: ssp: don't set ACE2.x LCTL::OFLEN

Browse source 
The OFLEN bit has to be set by the host driver for ACE2.x. The
ownership of the IP is now handled at the host driver level, no longer
the firmware.

Setting it at the firmware level is a no-op if the bit is already set
by the host driver, and will fail it isn't already set.
