Use a more generic console_init() instead of potato_uart_init(),
and do the same for interrupt control. There should be no
change in behaviour.

It makes things a bit more standard and a bit nicer to read
without all those strlen(). Also console.c takes care of adding
the carriage returns before the linefeeds.

Currently hello_world fails to build with distro cross compiler
packages such as Debian gcc-powerpc64-linux-gnu, because it doesn't
provide string.h or unistd.h. In fact we don't need them, we just
need stddef.h. This adds #include <stddef.h> to console.h to get
size_t defined. We also add #include "console.h" to console.c.
The hello_world Makefile currently hard-codes CROSS_COMPILE on
non-PPC machines. This means that a command like:
$ CROSS_COMPILE=powerpc64le-linux-gnu- make
doesn't do what you expect; it just tries to use powerpc64le-linux-gcc
regardless. Adding a '?' makes it do what one expects.
