ASoC: samsung: i2s: drop secondary DAI for i2sv7 hardware variant
Commit 9167f260477b ("ASoC: soc-generic-dmaengine: Handle DMA channel request failures correctly") started reporting DMA channel request failures during probe instead of silently ignoring them. This exposed a bug in the Samsung I2S driver: it always registered a second DAI and its associated "tx-sec" DMA channel, even for hardware variants that don't actually support it, such as i2sv7 used on Exynos5433. As a result, sound card probing on Exynos5433-based boards started failing, whereas previously it worked only because the channel request failure was ignored. Drop the QUIRK_SEC_DAI flag from i2sv7, since this variant does not have a secondary DAI and register "Secondary Playback" DAPM route only for variants with such interface.
