This patch fixes a null pointer exception caused by removal of
'ack()' for level interrupts in the Xilinx interrupt driver. A recent
change to the xilinx interrupt controller removed the ack hook for
level irqs.

This patch refactors some of the xilinx_intc interrupt controller driver
and adds support for cascading an i8259 off one of the irq lines.
This patch was based on the ML510 support work done by Roderick
Colenbrander.

The interrupt controller was not handling level interrupts correctly
such that duplicate interrupts were happening. This fixes the problem
and adds edge type interrupts which are needed in Xilinx hardware.

Various printk format string in code used by the Xilinx Virtex platform
are not 32-bit/64-bit safe. Add correct casting to fix the bugs.
