ASoC: rsnd: ssiu: Add shared SSI reset controller support

Browse source

The RZ/G3E SoC exposes a single shared "ssi-all" reset that gates all
SSI/SSIU modules. Acquire it at SSIU probe and pass it through
rsnd_mod_init() so it is wired into the rsnd_mod->rstc plumbing.

devm_reset_control_get_optional_shared() returns NULL when no reset is
described in DT, leaving existing R-Car generations unaffected.
