mb/google/nissa/var/anraggar: Enable BT audio offload
This patch enables Cnvi BT Audio Offload feature and also
configures the virtual GPIO for CNVi Bluetooth I2S pads.
BUG=b:303157827
TEST=Build and boot to anraggar. Verify the config from serial logs.

```
[SPEW ] -- CNVi Config --
[SPEW ] CNVi Mode= 1
[SPEW ] Wi-Fi Core= 1
[SPEW ] BT Core= 1
[SPEW ] BT Audio Offload= 0
[SPEW ] Pin Muxing
