The existing code can be both improved and simplified. To make this
change easier to manage, first add new implementation and then remove
deadcode in a separate patch.
Simplification achieved with:
- reduce the amount of resources requested by the driver i.e.: IPC and
CLDMA request_irq() merged into one
- reduce the number of DSP ops from 2 to 1:
irq_handler/thread() vs dsp_interrupt()
- drop ambiguity around CLDMA interrupt, let skl.c handle that
explicitly as it is the only user

While stream_tag for CLDMA on SKL-based platforms is always 1, function
hda_cldma_setup() uses AZX_SD_CTL_STRM() macro which does:
stream_tag << 20
what combined with stream_tag type of 'unsigned int' generates a
potential overflow issue. Update the field type to fix that.
