Sylwester Nawrocki 7e5d8706dd ASoC: samsung: i2s: Add missing assignment of variant_regs 
Add assignment of the variant_regs field which is missing in commit
a5a56871f8 ("ASoC: samsung: add support
for exynos7 I2S controller"). Without this attempting to probe the
secondary DAI fails with an error like:
