The single helper for both enable and disable cases is too complicated,
especially if we start adding more code to these helpers. Split it into
irq_enable and irq_disable cases.

Was it intentional to re-use this trace and not add a new one for
dpu_encoder_phys_cmd_irq_enable/dpu_encoder_phys_cmd_irq_disable?
Just thinking if the trace names Vs function names not matching would
become confusing.
