[XenPPC] [PATCH 0 of 2] [PATCH][UPDATED] move devtree creation to libxc

[Ryan Harper <ryanh@xxxxxxxxxx>]

Updated patchset rebased on 13943:5568efb41da4.

Changes include feedback from Jimi:
- Drop MIN() from read() in readfile()
- renamed find_cpu to find_cpu0 as we _are_ looking for cpu0
- modified find_cpu0 to check the 'reg' property for value 0 to
  confirm the node is cpu0.
- fixed bug in match(); use strlen() rather than sizeof()
- skip checking for NULLs passed to match()
- check snprintf() return vs buffer len rather than rv < 0
- remove hard-coded PHANDLE, add get_phandle() for static
  increasing value.
- moved rma_log out into xc_linux_build()
- re-ordered xc_linux_build() to load initrd if present and
  pass initrd base and length to make_devtree()
- make_devtree() now only reserves initrd space if needed
- changed rma reservation to be relative to rma_bytes
- changed remaining memory node-name to memory@<rma_bytes>
- changed dtb outputfile back to /tmp/domU.dtb
- removed get_rma_pages from util.c, use rma_log to calc rma_pages now.
- killed load_devtree()
- removed all ft_*() calls from xc_linux_build() as make_devtree()
  does it all.
- removed devtree arg from creat_start_info()
- updated copyright header in touched files.
