Simon Glass bbbe55f6f2 x86: Enable debug UART for Minnowmax
Enable the debug UART and emit a single 'a' early in the init sequence to
show that it is working.

Unfortunately the debug UART implementation needs a stack to work. I cannot
seem to remove this limitation as the absolute 'jmp %eax' instruction goes
off into the weeds.

So this means that the character output cannot be any earlier than
car_init_ret, where memory is available for a stack.
