is this not depends on COMMON_CLK and select SND_SOC_MT6358/6359 not 
require ?

obj-$(CONFIG_SND_SOC_MT8196) += mt8196/ should be after mt8195.

need to follow right sequence like mediatek/mt8195/Makefile

header required to be in a sequence. easy to read!
#include "mt8196-afe-clk.h"
#include "mt8196-afe-common.h"
#include "mtk-afe-fe-dai.h"
#include "mtk-afe-platform-driver.h"
