powerpc: Move a bunch of ppc64 headers to include/asm-powerpc
... and also delete some that are no longer used because we already had an include/asm-powerpc version of the header. Signed-off-by: Paul Mackerras <paulus@samba.org>

39 * The dt struct contains the device tree structure, full pathes and
40 * property contents. The dt strings contain a separate block with just
41 * the strings for the property names, and is fully page aligned and
42 * self contained in a page, so that it can be kept around by the kernel,
43 * each property name appears only once in this page (cheap compression)

48 * ends when size is 0
