rp2/mpbthciport: Fix HCI UART config.

Browse Source 
Fixes are:
- The baudrate argument is a keyword arg, it was passed before as a
  positional arg.
- Use the port and baudrate arguments passed from higher level code instead
  of the hard-coded port ID and baudrate, which would allow HCI drivers to
  change baudrates.
- Increase UART char timeout and RX buffer size.
