[v2,RESEND] soc/fsl/qe: fix usb.c build errors

  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.

Fixes these build errors:

drivers/soc/fsl/qe/usb.o: in function `qe_usb_clock_set':
usb.c:(.text+0x1e): undefined reference to `qe_immr'
powerpc-linux-ld: usb.c:(.text+0x2a): undefined reference to `qe_immr'
powerpc-linux-ld: usb.c:(.text+0xbc): undefined reference to `qe_setbrg'
powerpc-linux-ld: usb.c:(.text+0xca): undefined reference to `cmxgcr_lock'
powerpc-linux-ld: usb.c:(.text+0xce): undefined reference to `cmxgcr_lock'

I can reproduce the build error and confirm the build dependency fix (but I
have no hardware for testing).
