[ Upstream commit 35c8ae25c4fdeabf490e005692795a3be17ca5f6 ]
The tracing capabilities for the speaker protection fw enabled via
commit c55b3e46cb99 ("ASoC: wm_adsp: Add trace caps to speaker
protection FW") are not be available on all platforms, such as the
Valve's Steam Deck which is based on the Halo Core DSP.
As a consequence, whenever the firmware is loaded, a rather misleading
'Failed to parse legacy: -19' error message is written to the kernel
ring buffer:

[ 291.172383] steamdeck kernel: cs35l41 spi-VLV1776:01: DSP1: Failed to parse legacy: -19
Update wm_adsp_buffer_init() to print a more descriptive info message
when wm_adsp_buffer_parse_legacy() returns -ENODEV.
