Subject: [PATCH 5/5] ASoC: mediatek: mt8195-afe-pcm: Clean up unnecessary functions

Function mt8195_afe_init_registers() performs just a single call to
regmap_multi_reg_write(), it returns int and it's not error checked;
move that call to the probe function and also add some error check.

While at it, also move the contents of mt8195_afe_parse_of() to the
probe function as well: since this is getting a handle to topckgen
and since that's optional, the ifdef for CONFIG_SND_SOC_MT6359 can
also be removed.
