[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.
