fbdev: add drawing functions for framebuffers in system RAM
The generic drawing functions (cfbimgblt, cfbcopyarea, cfbfillrect) assume that the framebuffer is in IO memory. However, we have 3 drivers (hecubafb, arcfb, and vfb) where the framebuffer is allocated from system RAM (via vmalloc). Using _raw_read/write and family for these drivers (as used in the cfb* functions) is illegal, especially in other platforms. Create 3 new drawing functions, based almost entirely from the original except that the framebuffer memory is assumed to be in system RAM. These are named as sysimgblt, syscopyarea, and sysfillrect.
