[POWERPC] PS3: System manager re-work
PS3 sys-manager updates to reflect the new PS3 unifed device support. Fixups to the PS3 sys-manager driver to properly support sys_reboot(). - Add varable request_tag to struct ps3_sys_manager_header. - Move ctrl_alt_del from PS3_SM_EVENT_POWER_RELEASED to PS3_SM_EVENT_POWER_PRESSED. - Make the PS3 sys-manager driver a loadable module. - Add new file sys-manager-core.c. - Add new struct ps3_sys_manager_ops for dynamic binding. - Put data sent to device on stack. - Add support for PS3_SM_SERVICE_ID_REQUEST_ERROR. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
