powerpc/qe&cpm2: Avoid redefinitions in CPM2 and QE headers

Browse Source 
struct mcc defined in both immap_qe.h and immap_cpm2.h, so they will
conflic when included in a single file. The mcc struct is easy to deal
with, since it isn't used in any driver (yet), so let's just rename QE
version to qe_mcc.

The ucb_ctlr is a bit trickier, since it is used by fsl_qe_udc driver,
and the driver supports both CPM and QE UDCs, plus the QE version is
used to form a bigger immap struct.

I don't want to touch too much of USB code in this series, so for now
let's just copy most generic version into the common cpm.h header,
later we'll create cpm_usb.h where we'll place common USB structs that
are used by QE/CPM UDC and QE Host drivers (FHCI).

And as for the structs in qe.h and cpm2.h, just prefix them with qe_
and cpm_.
