fbdev: add fb_read/fb_write functions for framebuffers in system RAM
The functions fb_read() and fb_write in fbmem.c 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/__raw_write (fb_readl/fb_writel) for these drivers is illegal, especially in other platforms. Create file read and write methods for these types of drivers. These are named fb_sys_read() and fb_sys_write().
