Benjamin Herrenschmidt c5f5f50738 hello_world: Use new headers and frequency from syscon
This uses the new header files for register definitions and
extracts the core frequency from syscon rather than hard coding it.

This is one step towards ultimately removing the address-based
cache inhibit hack from dcache.vhdl.

Paul Mackerras abefafd70b hello_world: Adjust header inclusions and Makefile
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.
