imxfb: remove ifdefs

Here are some small fixes for the imxfb framebuffer driver:

 - remove ifndef for MX1FS2 platform which is not present in the kernel.
 - REV, CLS, PS and SPL_SPR are only needed with some sharp displays.
   Only setup the corresponding io pins when such a display is connected.
