fbdev: sisfb: hide unused variables

Building with W=1 shows that a couple of variables in this driver are only
used in certain configurations:

This started showing up after the definitions were moved into the
source file from the header, which was not flagged by the compiler.
Move the definition into the appropriate #ifdef block that already
exists next to them.
