Consolidate ATA, ePORT, QSPI, FlexCan, PWM, RNG, MDHA, SKHA, INTC, and FlexBus structures and definitions in immap_5xxx.h to more unify modules header files. Append DSPI support for m547x_8x. SSI cleanup. Remove USB Host structure from immap_539.h. Apply changes to use FlexBus structures in mcf52x2's cpu_init.c and platform configuration files.
