I see no relevant changes in exynos_defconfig between v4.7..v4.8 and also no changes in drivers/Makefile that could cause things to be initialized on a different order.
I remember this
commit 6eb1c9496b81680f2cd2e0eda06c531317e2e28d clk: probe common clock drivers earlier
going in recently, but it's rather dubious it could cause such trouble.
Anyway, I'd try to add some debug prints to samsung_i2s_probe() to see what's the issue with the CPU DAI registration.
fyi, Marek already fixed this issue on patch "ASoC: samsung: get access to DMA engine early to defer probe properly":
