ASoC: SOF: ipc4: Use generic function for mapping "exception" debugfs file

Remove sof_ipc4_create_exception_debugfs_node() and ipc4-telemetry.c,
and use sof_ipc4_create_debug_slot_ro_debugfs_node() instead for
mapping "exception" debugfs file.

In running system the SOF_IPC4_DEBUG_SLOT_TELEMETRY is used for
telemetry data, but if configured, Zephyr exception data is dumped in
the same debug window slot, right after the separator word.
