Davinci: aintc/cpintc - use ioremap()
This patch implements the following:
- interrupt initialization uses ioremap() instead of passing a virtual address
via davinci_soc_info.
- machine definitions directly point to cp_intc_init() or davinci_irq_init()
- davinci_intc_type and davinci_intc_base now get initialized in controller
specific init functions instead of davinci_common_init()
- minor fix in davinci_irq_init() to use intc_irq_num instead of
DAVINCI_N_AINTC_IRQ
