Use the SoC infrastructure to hold the interrupt controller information (i.e., base address, default priorities, interrupt controller type, and the number of IRQs). The interrupt controller base, although initially put in the soc_info structure's intc_base field, is eventually put in the global 'davinci_intc_base' so the low-level interrupt code can access it without a dereference. These changes enable the SoC default irq priorities to be put in the SoC-specific files, and the interrupt controller to be at any base address. Signed-off-by: Mark A.
