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

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.

ASoC: SOF: Rename sof_arch_ops to dsp_arch_ops

From the name sof_arch_ops one can not decipher that these ops are DSP
architecture ops.
Rename it to dsp_arch_ops and change also the macro to retrieve the DSP
architecture specific ops as well.

ASoC: SOF: fix DSP oops definitions in FW ABI

The definitions for DSP oops structures were not aligned
correctly to current FW ABI version 3.6.0, leading to
invalid data being printed out to debug logs. Fix the structs
and update related platform code accordingly.
