irq_domain/microblaze: Convert microblaze to use irq_domains
This patch converts Microblaze to use the irq_domain remapper and get away from hard coding the offset between hwirq number and the linux irq number space. This also paves the way for multiple interrupt controllers. v2: Don't enable SPARSE_IRQ and keep NR_IRQS set to 33 Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Michal Simek <monstr@monstr.eu> Cc: Rob Herring <rob.herring@calxeda.com> Cc: John Williams <john.williams@petalogix.com> Cc: John Linn <john.linn@xilinx.com>
