ls1 has qe and ls1 has arm cpu.
move qe from arch/powerpc to drivers/soc/fsl
to adapt to powerpc and arm
Signed-off-by: Zhao Qiang <B45475@freescale•com>

Changes for v2:
- move code to driver/soc
Changes for v3:
- change drivers/soc/qe to drivers/soc/fsl-qe
Changes for v4:
- move drivers/soc/fsl-qe to drivers/soc/fsl/qe
- move head files for qe from include/linux/fsl to include/soc/fsl
- move qe_ic.c to drivers/irqchip/
Changes for v5:
- update MAINTAINERS

You forgot to change "Orphan" to "Maintained" and designate a
maintainer.
Who is going to do the additional work to make this usable on ARM?
Who is going to merge those patches?

The whole point of this move is to let the code be used on more than
just powerpc, so fix the rheap and other obvious PPC dependencies
first.
