It is way too easy to miss enabling SERIAL_OF_PLATFORM which would
result in the inability for the kernel to have a valid console device,
which can be seen with:
Warning: unable to open an initial console.
and then:
Run /init as init process
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000100
Since SERIAL_OF_PLATFORM already depends on SERIAL_8250 && OF there
really is no drawback to defaulting this config to the value of
SERIAL_8250.
