[PATCH v3] ASoC: update outdated comments for removed snd_soc_new_pcms()

[Kexin Sun]

The function snd_soc_new_pcms() was removed during the
multi-component refactoring in commit f0fba2ad1b6b ("ASoC:
multi-component - ASoC Multi-Component Support").  Its PCM creation
role is now handled by soc_new_pcm(), which was later moved to
sound/soc/soc-pcm.c by commit ddee627cf6bb ("ASoC: core - Separate
out PCM operations into new file.").

In fsl_dma.c, update the comment to reference soc_new_pcm().  Also
remove the stale paragraph about snd_dma_alloc_pages() always
allocating in lowmem, since commit e159704f7920 ("ASoC: fsl_dma:
Use managed buffer allocation") replaced that call with
snd_pcm_set_fixed_buffer_all().

In siu_pcm.c, remove the stale comment referencing
snd_soc_new_pcms() and the no-longer-existing socdev structure.

v3:
 - Drop "via the pcm_construct callback" from fsl_dma.c comment (Mark Brown)

v2:
 - Also fix the stale comment in siu_pcm.c
