[PATCH] powerpc/fsl: mpic timer driver

From: Wang Dongsheng <Dongsheng.Wang <at> freescale.com>

Global timers A and B internal to the PIC. The two independent groups
of global timer, group A and group B, are identical in their functionality.
The hardware timer generates an interrupt on every timer cycle.
e.g
Power management can use the hardware timer to wake up the machine.
