ASoC: SOF: Intel: hda: Keep non-alt mlinks powered at probe on ACE2+

Drop the hda_bus_ml_put_all() call at the end of hda_init_caps().

On multi-link (mlink) capable platforms the non-alternate links
(HDaudio and iDisp) are powered on by hardware when CRST# is
de-asserted (LCTL.SPA = 1) and their ref_count is pre-charged to 1 in
hda_ml_alloc_h2link() to match this state. The put_all call
immediately dropped that reference and toggled LCTL.SPA back to 0,
relying on the first stream open to power the link up again.

On ACE2+ platforms this redundant SPA 1->0->1 toggle at probe leaves
the Processing Pipe Capability (PPLC) Linear Link Position counters in
a state where they do not advance on the first stream after boot. The
counters only start working after the first full runtime suspend/resume
cycle, which includes a CRST# assert/deassert that fully resets the PPC
AON block.

Keep the non-alt links powered from CRST# de-assert through first use.
System suspend still powers them down via hda_bus_ml_suspend(), and
resume relies on CRST# de-assert to bring them back up, so no other
path is affected.
