[PATCH,v2 00/28] powerpc: irq_data conversion.

This patch converts powerpc over to the new irq_data based irq_chip functions, as was done earlier for ARM and most other architectures. struct irq_data is described here: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=ff7dcd44dd446db2c3e13bdedf2d52b8e0127f16
