ARM: clps711x: Remove board support for CEIVA 

The current kernel does not fit in the CEIVA ROM. Also, some functional
has already been removed due migrate from 2.6 to 3.0, and it seems that
no one uses this platform. So, remove support for this board and modules
specific only to this board.

*
* Noteworthy Issues
* -----------------
*
* This driver is complicated by the fact that this is a 16-bit chip
* and, on at least one platform (ceiva), we can only do 16-bit reads
* and writes to the framebuffer. We hide this from user space
* except in the case of mmap().
*
*
* To Do
* -----
*
* - Test 8-bit pseudocolor mode
* - Allow setting bpp, virtual resolution
* - Implement horizontal panning
* - (maybe) Implement hardware cursor
