fbdev/leo: Use initializer macro for struct fb_ops

Initialize struct fb_ops to the correct default values with the
macro FB_DEFAULT_SBUS_OPS(). Rename the ioctl and mmap callbacks
to use the infix _sbusfb_. This makes them fit the SBUS helpers'
naming pattern. Also make the driver depend on FB_SBUS_HELPERS,
which selects the correct modules.
