hal: Check to ensure that backend is configured with correct sample rate

- Backend sample rates of greater than 48Khz are only supported on

- With internal codec, the supported sample rate is only 48Khz.
- Add a check to ensure that the sample rate is set to default sample
rate for devices having internal codec.
