ncs 2.7.0 RC error with i2s initialization

Question

We have an issue with initializing our i2s instance as mentioned in sample code with an `id` of `0`: 
 // Instance of NRFX I2S driver (there is only one I2S instance in the system).
static nrfx_i2s_t omni_mic_instance = NRFX_I2S_INSTANCE(0);

We get this error: 
 /opt/nordic/ncs/v2.7.0/modules/hal/nordic/nrfx/drivers/include/nrfx_i2s.h:115:33: error: 'NRF_DT_N_S_soc_S_peripheral_50000000_S_i2s_280000' undeclared here (not in a function); did you mean 'DT_N_S_soc_S_peripheral_50000000_S_i2s_28000_ORD'?

To fix we reverted back to the 2.6.1 code instead of using ` NRFX_CONCAT (NRF_, I2S, id)` in `nrfx_i2s.h` : 
 #define NRFX_I2S_INSTANCE(id)
.p_reg = NRF_I2S##id,
