[PATCH 33/37] powerpc: spider-pic: get pic from chip_data instead of irq_map

[Milton Miller]

Building on Grant's efforts to remove the irq_map array, this patch
moves spider-pics use of virq_to_host() to use irq_data_get_chip_data
and sets the irq chip data in the map call, like most other interrupt
controllers in powerpc.
