ppc: cleanup register types

- use target_ulong for gpr and dyngen registers - remove ppc_gpr_t type - define 64-bit dyngen registers for GPE register on 32-bit targets Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5154 c046a42c-6fe2-441c-8c8c-71466251a162
