arch, devices: move serial creation to arch

Split the serial code  into two parts:

- Configuration and setup: arch/src/serial.rs
- Serial device emulation: devices/src/serial.rs

No change in functionality - this is just preparation for generalizing
the command line parsing/setup code so that it can be used with virtio
console devices as well.
