Blue Swirl b00e6c7085 sparc32: fix warnings from GCC 4.6.0 ...

Compiling Sparc32 with GCC 4.6.0 20100925 produced a few warnings:
../arch/sparc32/context.c: In function 'start_main':
../arch/sparc32/context.c:49:9: error: variable 'retval' set but not used [-Werror=unused-but-set-variable]
../arch/sparc32/romvec.c: In function 'obp_devwrite':
../arch/sparc32/romvec.c:326:9: error: variable 'ret' set but not used [-Werror=unused-but-set-variable]
../drivers/iommu.c: In function 'iommu_init':
../drivers/iommu.c:102:24: error: variable 'vers' set but not used [-Werror=unused-but-set-variable]
../drivers/iommu.c:102:18: error: variable 'impl' set but not used [-Werror=unused-but-set-variable]

Fix the warnings by avoiding write-only variables.
