arm_fpga: Read GICD and GICR base addresses from DT

Since we use a DTB with all platform information to pass this on to a
kernel loaded as BL33, we can as well make use of it for our own
purposes.

Every DT would contain a node for the GIC(v3) interrupt controller, so
we can read the base address for the distributor and redistributors from
there.

This avoids hard coding this information in the code and allows for a more
flexible binary.
