Fix build errors in soc/fsl/qe/usb.c when QUICC_ENGINE is not set. This happens when PPC_EP88XC is set, which selects CPM1 & CPM. When CPM is set, USB_FSL_QE can be set without QUICC_ENGINE being set. When USB_FSL_QE is set, QE_USB deafults to y, which causes build errors when QUICC_ENGINE is not set. Making QE_USB depend on QUICC_ENGINE prevents QE_USB from defaulting to y.
