fbdev/vt8500lcdfb: Initialize fb_ops with fbdev macros
Initialize the instance of struct fb_ops with fbdev initializer macros for framebuffers in DMA-able virtual address space. Set the read/write, draw and mmap callbacks to the correct implementation and avoid implicit defaults. Also select the necessary helpers in Kconfig. Fbdev drivers sometimes rely on the callbacks being NULL for a default I/O-memory-based implementation to be invoked; hence requiring the I/O helpers to be built in any case. Setting all callbacks in all drivers explicitly will allow to make the I/O helpers optional. This benefits systems that do not use these functions.
