PATCH 1/1 powerpc: 85xx: Modify CONFIG_USB_MAX_CONTROLLER_COUNT for P1022DS

From: Ying Zhang <[email protected]>

Modify CONFIG_USB_MAX_CONTROLLER_COUNT value to 1 on P1022DS. As ETSEC2 and USB2 are muxed; thus if ETSEC2 is enabled, the system bus hangs on USB2 if ETSEC2 is enabled but "usb start" command is issued. Hence making default controller count to 1 to avoid system hang.
