powerpc: Make CMO paging space pool ID and page size available
During platform setup, save off the primary/secondary paging space pool IDs and the page size. Added accessors in hvcall.h for these variables. This is needed for a subsequent fix. Submitted-by: Robert Jennings <rcj@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
