[PATCH v4 01/26] hw/ppc/e500: Do not leak struct boot_info

[Bernhard Beschow <shentey@gmail.com>]

The struct is allocated once with g_new0() but never free()'d. Fix the leakage
by adding an attribute to struct PPCE500MachineState which avoids the
allocation.

While at it remove the obsolete /*< private >*/ markers.
