drivers/ninaw10/nina_bt_hci: Make some minor fixes to HCI driver.

Browse Source 
Fixes are:
- Reset the module first before changing GPIO1 direction.
- Skip spurious bytes received after reset.
- Use HCI UART ID and baudrate when reinitializing UART.
- Disable all printf output which causes unit-tests to fail.
