Add initializer macros for struct fb_ops of drivers that operate on SBUS-based framebuffers. Also add a Kconfig token to select the correct dependencies. All drivers for SBUS-based framebuffers use the regular helpers for framebuffers in I/O memory (fb_io_*() and cfb_*()). Each driver provides its own implementation of mmap and ioctls around common helpers from sbuslib.o. Patches 1 to 3 clean up the code a bit and add a initializer macros that set up struct fb_ops correctly. Patches 4 to 11 convert the drivers. Each patch slightly renames the driver's mmap and ioctl functions so that it matches the name pattern of sbuslib.o. Like the other fbdev initializer macros, the SBUS helpers are easily grep-able. In a later patch, they can be left to empty values if the rsp. functionality, such as file I/O or console, has been disabled. There are no functional changes. The helpers set the defaults that the drivers already use. The fb_io_*() functions that the initializer macro sets are the defaults if struct fb_ops.fb_read or .fb_write are NULL. After all drivers have been updated to set them explicitly, the defaults can be dropped and the functions can be made optional. Build-tested on sparc64.
