The reg structures are already into these header files - the patch moves
only the bit meaning inside the imx-regs.h files. We can discuss if we
should move them again into the driver, making the decision on which
structure to be used not on a SOC level (#ifdef CONFIG_MXxx), but on
basis of the controller type (CSPI or ECSPI).

This makes sense if we run (we had until now no use case with the
currently supported boards) a MX5 board using a CSPI instead of a ECSPI.
In this case, we should also transform MXC_CSPI / MXC_ECSPI in a CONFIG_
define to be put in the board configuration file.

However, as usual in u-boot, dead code or code that has no use case and
cannot be tested is not allowed. Until we have not such a board (MX5
board requiring CSPI instead of ECSPI), we should avoid to introduce not
tested code and let those changes for a next patch.
