[PATCH 2/2 v3] powerpc/85xx: Abstract common define of signal multiplex control for qe

[Zhicheng Fan]

From: Zhicheng Fan <b32736 at freescale.com>

The mpc85xx_rdb and mpc85xx_mds have commom define of signal multiplex for qe ,so
they need to go in common header, the patch abstract them to fsl_guts.h
