soundwire: bus: don't clear SDCA_CASCADE bit
The SDCA_CASCADE bit is a SoundWire 1.2 addition. It is technically in
the DP0_INT register, but SDCA interrupts shall not be handled as part
of the DP0 interrupt processing.
The existing code has clear comments that we don't want to touch the
SDCA_CASCADE bit, but it's actually cleared due to faulty logic dating
from SoundWire 1.0
In theory clearing this bit should have no effect: a cascade bit
remains set while all ORed status are set, but better safe than sorry.
