This PR fixes pin assignments of I2S_SDIN/SDOUT of Wio Terminal, added at #4679. The initial implementation followed the schematics (https://files.seeedstudio.com/wiki/Wio-Terminal/res/Wio-Terminal-SCH-v1.2.pdf), where I2S_SDIN and I2S_SDOUT are defined as PA21(SDO) and PA22(SDI), respectively. This PR swaps the definitions to be consistent with other boards.
