[PATCH] video: fbdev: savage: savagefb.h: Cleaning up variable that is never used

[Rickard Strandqvist <rickard_strandqvist@spectrumdigital.se>]

From: Rickard Strandqvist <rickard.strandqvist@sonymobile.com>

Variable ar assigned a value that is never used.
I have also removed all the code that thereby serves no purpose.

This was found using a static code analysis program called cppcheck
