[PATCH 4/5] Set RC of mpc8641 to transparent bridge for transfer legacy I/O access.

[Zhang Wei]

Set RC of mpc8641 to transparent bridge for transfer legacy I/O access.
Now, the children bus could use the I/O resource of the host bridge.

Note: The 0x7010 is the device ID of host bridge for MPC8641 and
0x7011 is the device ID of host bridge fro MPC8641D.
