mb/prodrive/hermes: Fix 30 second boot delay 

The PMC doesn't response any more due to invalid CNVi GPIO
configuration. This caused a 30 second boot delay in FSP-S.

Use the same values as FSP-S does. Always disable external I2S BT
audio and use NF3 for pad GPP_D5 and GPP_D6.

Tested on Prodrive hermes:
No boot delay can be observed any more.
