Remove tsec_t typedef. Define macros as getters of tsec and mdio register memory regions, for consistent initialization of various 'regs' fields and also to manage overly long initialization lines. Use the __iomem address space marker to address sparse warnings in tsec.c where IO accessors are used, like:
tsec.c:394:19: warning: incorrect type in argument 1 (different address spaces) tsec.c:394:19: expected unsigned int volatile [noderef] asn:2*addr tsec.c:394:19: got unsigned int *<noident> [...]
Add the __iomem address space marker for the tsec pointers to struct tsec_mii_mng memory mapped register regions. This solves the sparse warnings for mixig normal pointers with __iomem pointers for tsec.
