tests: drivers: i2s: Add i2s_additional tests
Extend I2S testing with additional test cases that verify I2S/TDM driver operation at various configurations. Check: - word sizes of 8, 16, 24, 32 and 48 bits; - one, two, four and eight audio channels configuration; - data format I2S, Left Justified, Right Justified, PCM Long, PCM Short; - data order MSB and LSB first; - bit clock and frame clock inversion; - block size of 6 bytes; - bit clock continuous and gated; - internal loopback; - pingpong option. Signed-off-by: Sebastian Głąb <sebastian.glab@nordicsemi.no>
