[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.
