[PATCH] i.MX framebuffer remove ifdefs

[PATCH] i.MX framebuffer remove ifdefs

[Sascha Hauer]

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.
