[PATCH 2/2] ASoC: mediatek: mt8183: Fix UL1_CH2 I2S0_CH2 routing register

[HuskerMinion via B4 Relay]

From: HuskerMinion <mocker-mug-unwoven@xxxxxxxx>

The "I2S0_CH2" switch of the UL1_CH2 mixer writes AFE_CONN21. That is
the interconnect register for UL1 channel 1 (O21). Channel 2 is O22,
which is AFE_CONN22, as the "ADDA_UL_CH2" switch of the same mixer
already uses.

So enabling the switch routes I2S0 channel 2 into UL1 channel 1, mixed
with channel 1, and UL1 channel 2 gets nothing from I2S0.

Use AFE_CONN22.

Found while adding UL1 capture routes for the four microphones of the
Amazon Echo Show 8 (2nd gen). That board captures from I2S2, so the
I2S0 path itself is only compile tested.

Fixes: d232591c9482 ("ASoC: Mediatek: MT8183: add I2S2 control path from UL2 and UL3")
