[RFC PATCH v9 6/6] topology, cleanup: Avoid redefinition of cpumask_of_pcibus in asm header files.

[Ganapatrao Kulkarni]

At present cpumask_of_pcibus is defined for !CONFIG_NUMA and moving out
to common will allow to use for numa too. This also avoids
redefinition of this macro in respective architecture header files.
