ASoC: rsnd: Add SSI reset support for RZ/G3E platform
Acquire the per-SSI reset controller and pass it through
rsnd_mod_init() so it is wired into the rsnd_mod->rstc plumbing.
The RZ/G3E SoC exposes one reset line per SSI instance. Use the
indexed-name rsnd_devm_reset_control_get_optional_indexed() helper
so the same code accepts both the hyphenated RZ/G3E names
("ssi-0", "ssi-1", ...) and the legacy dotted names used by R-Car
("ssi.0", ...).
The helper returns NULL when no reset is described in DT, leaving
existing R-Car generations unaffected.
