drivers: i2s: Introduce the I2S_DIR_BOTH enumeration value

Browse source 
Introduce a new enumeration value that allows setting configuration
and triggering commands for both I2S streams simultaneously.
Such possibility is especially important on hardware where the streams
can be only enabled/disabled (but not started/stopped) independently,
like it is in nRF SoCs.
