arm64: Convert dts to use reserved-memory nodes
Device tree regions described by /memreserve/ entries are not available in
/proc/device-tree, and hence are not available to user space utilities that use
/proc/device-tree. In order for these regions to be available, convert any
arm64 DTS files using /memreserve/ entries to use reserved-memory nodes.
This change is required for kexec re-boot to work properly when a user does not
specify a second stage DTB via the kexec --dtb option. When the --dtb option is
not specified kexec will prepare the second stage DTB using data from
/proc/device-tree.
