Fix spiFlash type mismatch warning during init (#2809)

This PR makes a small change to Host builds, enabling all `debug_x` statements during init/exit.
This highlights one issue, fixed, caused by missing device entry in Rp2040, Host hardware configs:
    
```
[Device] 'spiFlash' type mismatch, 'unknown' in partition table but device reports 'flash'
```
