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

[Vitaly Bordug <vbordug@ru.mvista.com>]

[-- Attachment #1: Type: text/plain, Size: 542 bytes --]

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.
