fbdev/wm8505fb: Initialize fb_ops to fbdev I/O-memory helpers
Initialize the instance of struct fb_ops with fbdev initializer
macros for framebuffers in DMA-able address space. This explictily
sets the read/write, draw and mmap callbacks to the correct default
implementation. Also select the necessary helpers in Kconfig.
Fbdev drivers sometimes rely on the callbacks being NULL for a
default implementation to be invoked; hence requireing 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.
Set the callbacks via macros. No functional changes.
