powerpc/qe&cpm2: Avoid redefinitions in CPM2 and QE headers
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_. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
