QEIC was supported on PowerPC, and dependent on PPC,
Now it is supported on other platforms, so remove PPCisms.

qeic_of_init just get device_node of qeic from dtb and call qe_ic_init,
pass the device_node to qe_ic_init.
So merge qeic_of_init into qe_ic_init to get the qeic node in
qe_ic_init.

The codes of qe_ic init from a variety of platforms are redundant,
merge them to a common function and put it to irqchip/irq-qeic.c
For non-p1021_mds mpc85xx_mds boards, use "qe_ic_init(np, 0,
qe_ic_cascade_low_mpic, qe_ic_cascade_high_mpic);" instead of
"qe_ic_init(np, 0, qe_ic_cascade_muxed_mpic, NULL);".
qe_ic_cascade_muxed_mpic was used for boards has the same interrupt
number for low interrupt and high interrupt, qe_ic_init has checked
if "low interrupt == high interrupt"
