skd: Fix checkpatch ERRORS and removed unused functions
This patch fixes checkpatch.pl errors for assignment in if condition. It also removes unused readq / readl function calls. As Andrew had disabled the compilation of drivers for 32 bit, I have modified format specifiers in few VPRINTKs to avoid warnings during 64 bit compilation.
