ASoC: rockchip: Fix mono capture [ Upstream commit 789e162a6255325325bd321ab0cd51dc7e285054 ] This reverts commit db51707b9c9aeedd310ebce60f15d5bb006567e0. Revert "ASoC: rockchip: i2s: Support mono capture" Previous discussion in https://patchwork.kernel.org/patch/10147153/ explains the issue of the patch. While device is configured as 1-ch, hardware is still generating a 2-ch stream. When user space reads the data and assumes it is a 1-ch stream, the rate will be slower by 2x. Revert the change so 1-ch is not supported. User space can selectively take one channel data out of two channel if 1-ch is preferred. Currently, both channels record identical data.
