[PATCH] ppc32: Add ppc_sys descriptions for PowerQUICC I devices

Added ppc_sys device and system definitions for PowerQUICC I devices.  This
will allow drivers for PQI to be proper platform device drivers.  Currently
sys section contains only MPC885 and MPC866.  Identification should be done
with identify_ppc_sys_by_name call, with board-specific "name" string
passed, since PQI do not have any register that could identify the SOC.
