use the standard framebuffer_alloc() and framebuffer_release() instead of custom defined function. for making that change we had to change a member of the private structure from a variable to pointer and had to touch almost all places of the file. since fb was changed into a pointer so all instance of "sfb->fb." has been changed into "sfb->fb->". now we will get build warning about smtc_alloc_fb_info() and smtc_free_fb_info() to be unused which will be removed in the next patch of the series.
