ASoC: SOF: Intel: hda-stream: fix a deadlock with bus->reg_lock

We should use irq disabled mode when read/write hda registers from
thread context, as we need to hold the same bus->reg_lock in interrupt
context hda_dsp_stream_interrupt(), otherwise, when we are holding the
lock in hda_dsp_stream_hw_free() and the interrupt arrives, we will get
deadlock in the interrupt handler.

Error logs like this:

The fix is simple, let's switch to use spin_lock/unlock_irq().
