target-arm: Make IRQ and FIQ gpio lines on the CPU object

Now that ARMCPU is a subclass of DeviceState, we can make the
CPU's inbound IRQ and FIQ lines be simply gpio lines, which
means we can remove the odd arm_pic shim.

We retain the arm_pic_init_cpu() function as a backwards
compatibility shim layer so we can convert the board models
to get the IRQ and FIQ lines directly from the ARMCPU
object one at a time.
