> 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
