MPC834x USB patches

MPC834x USB patches. The first is quite serious and would be nice to get in 2.6.23.

mpc834x USB-MPH configuration got broken by commit 6f442560021aecf08658e26ed9a37e6928ef0fa1. The selection bits in SICRL should be cleared rather than set to configure the USB MUXes for the MPH.

Setup dr_mode for USB-DR to peripheral as the default (host mode) doesn't make much sense for the mini-AB connector on the ITX board.

Peripheral mode is preferable to OTG as the fsl_usb2_udc.c driver doesn't yet properly support it.
