mxc_spi: move machine specifics into CPU headers
Move (E)CSPI register declarations into the imx-regs.h files for each supported CPU
Introduce two new macros to control conditional setup
MXC_CSPI - Used for processors with the Configurable Serial Peripheral Interface (MX3x)
MXC_ECSPI - For processors with Enhanced Configurable... (MX5x, MX6x)
