we iterate over all the channels, and if more than one channel is active at a time. interrupt on any one of active channel was triggering callback for other active channel, because flags value is 1 (enabled). this is commit handle this behaviour and only trigger callback if bits other than status is set Signed-off-by: Anuj Pathak <anuj@croxel.com>

Description
Adds I2S driver for MAX32655 MCU. It was only tested on MAX32655FTHR board using
samples/i2s/echosample.Theoretically it should work on most MAS32 MCU (except MAX32650/MAX32660 which uses SPIMSS peripheral), given same MXC_I2S_* APIs and config structure are used internally. But due to lack of hardware it is not tested and dts of other mcu/board is also not updated.
