[PATCH 2/2] powerpc/pasemi: Drop redundant res assignment

[Krzysztof Kozlowski]

Return value of pas_add_bridge() is not used, so code can be simplified
to fix W=1 clang warnings:

  arch/powerpc/platforms/pasemi/pci.c:275:6: error: variable 'res' set but not used [-Werror,-Wunused-but-set-variable]
