irq_domain/microblaze: Convert microblaze to use irq_domains

Browse Source 
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
