ASoC: SOF: dsp_arch_ops: add kernel log level parameter for oops and stack

Browse source 
To allow custom log level to be used for the DSP oops and stack print, add
a kernel log level parameter to the two ops.

Modify the xtensa oops and stack functions tom use this new log level
parameter.

Pass KER_ERR from snd_sof_get_status() to make sure that there is no
functional change with this new parameter.
