apalis/colibri_t30: Add comments about i2s pin muxing/operation
Add a comment about DAP FS pin mux requiring INPUT when operating as I2S slave.
Add a comment about DAP SCLK requiring INPUT even when operating as I2S master.
Add a comment about is_i2s_master in the platform data meaning T30 SoC is I2S
master.
