driver(I2S): Fix i2s_comm_format_t configuration parameter does not match the TRM bug.

Browse Source 
When I2S `i2s_comm_format_t` is set to `I2S_COMM_FORMAT_I2S_MSB`, the data should launch at first BCK. But not in fact, this MR fixed this issue.

For compatibility, several nwe parameters have been added, and the old parameters will be removed in the future.
